OPINION OF ADVOCATE GENERAL
      LÉGER 
      delivered on 30 September 2003 (1)
      
      Case C-147/02
      M.K. Alabaster
      v
      Woolwich plc and
      Secretary of State for Social Security
      (Reference for a preliminary ruling from the Court of Appeal of England and Wales, Civil Division)
      (Social policy – Equal pay for men and women – Directive 92/85/EEC – Maternity leave – Maternity benefit based on the woman’s earnings – Pay rise before or during maternity leave – Whether to include)1.        This case provides an opportunity for the Court to clarify, or indeed reconsider, the case of Gillespie. (2) That case related to the principle of equal pay for men and women and, more particularly, women’s pay during their maternity
         leave.
      
      2.        In this case the Court of Appeal of England and Wales, Civil Division, (3) is asking whether Article 119 of the EC Treaty (Articles 117 to 120 of the EC Treaty have been replaced by Articles 136 EC
         to 143 EC) must be interpreted as meaning that, where statutory maternity pay is calculated on the basis of the woman’s average
         earnings during a specified period, such pay must include any pay rises awarded before or during the period of maternity leave
         but outside the reference period laid down by national law.
      
      I –  Legal background
      A –    Community law
      3.        Article 119 of the Treaty establishes the principle of equal pay for men and women. (4) It provides as follows:
      
      ‘Each Member State shall during the first stage ensure and subsequently maintain the application of the principle that men
         and women should receive equal pay for equal work.
      
      For the purpose of this Article, “pay” means the ordinary basic or minimum wage or salary and any other consideration, whether
         in cash or in kind, which the worker receives, whether directly or indirectly, in respect of his employment from his employer.’
      
      4.        According to Article 1 of Directive 75/117/EEC, (5) the principle of equal pay is intended to eliminate, for the same work or for work to which equal value is attributed, all
         discrimination on grounds of sex with regard to all aspects and conditions of remuneration.
      
      5.        Directive 76/207/EEC (6) establishes the principle of equal treatment of men and women for the purposes of access to employment and working conditions.
         (7) That principle is intended to remove any discrimination on grounds of sex, either directly or indirectly, by reference in
         particular to marital or family status. (8)
      
      6.        Article 2(3) of Directive 76/207 provides that the directive is without prejudice to provisions concerning the protection
         of women, particularly as regards pregnancy and maternity.
      
      7.        On 19 October 1992, the Council of the European Union adopted Directive 92/85/EEC on the introduction of measures to encourage
         improvements in the safety and health at work of pregnant workers and workers who have recently given birth or are breastfeeding
         (tenth individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC). (9) That directive is based on Article 118a of the EC Treaty (Articles 117 to 120 of the EC Treaty have been replaced by Articles
         136 EC to 143 EC) and was to be transposed by 19 October 1994. (10)
      
      8.        Article 8 of Directive 92/85 relates to maternity leave. It provides as follows:
      ‘(1)      Member States shall take the necessary measures to ensure that workers within the meaning of Article 2 are entitled to a continuous
         period of maternity leave of at least 14 weeks allocated before and/or after confinement in accordance with national legislation
         and/or practice.
      
      (2)      The maternity leave stipulated in paragraph 1 must include compulsory maternity leave of at least two weeks allocated before
         and/or after confinement in accordance with national legislation and/or practice.’
      
      9.        Article 11 of Directive 92/85 concerns employment rights. It provides as follows:
      ‘In order to guarantee workers within the meaning of Article 2 the exercise of their health and safety protection rights as
         recognised in this Article, it shall be provided that:
      
      ...
      (2)      in the case referred to in Article 8 [maternity leave], the following must be ensured:
      (a)      the rights connected with the employment contract of workers within the meaning of Article 2, other than those referred to
         in point (b) below; 
      
      (b)      maintenance of a payment to, and/or entitlement to an adequate allowance for, workers within the meaning of Article 2; 
      (3)      The allowance referred to in point 2(b) shall be deemed adequate if it guarantees income at least equivalent to that which
         the worker concerned would receive in the event of a break in her activities on grounds connected with her state of health,
         subject to any ceiling laid down under national legislation.’
      
      B –    National law
      10.      The national provisions on statutory maternity pay are found in Part XII of the Social Security Contributions and Benefits
         Act 1992 (‘the Act’).
      
      11.      Under section 164 of the Act, an employee is entitled to statutory maternity pay if she has been employed for a continuous
         period of at least 26 weeks with the same employer by the 15th week before the expected week of confinement, her normal weekly
         earnings are over a certain level, she has given the employer the appropriate notice and the baby is due within 11 weeks.
      
      12.      Under section 165(1) of the Act, statutory maternity pay is payable for a maximum of 18 weeks.
      13.      Section 166(1) of the Act provides that there are two rates of pay, the higher rate and the lower rate.
      14.      Section 166(2) of the Act prescribes that the higher rate is a rate equivalent to 90% of the woman’s normal weekly earnings
         for a period of eight weeks immediately preceding the 14th week before the expected week of confinement or the lower rate,
         whichever is the higher. The lower rate is a flat-rate weekly payment.
      
      15.      Under section 166(1) and (4) of the Act, where an employee is entitled to higher rate statutory maternity pay, she is entitled
         to the higher rate for six weeks and to the lower rate for 12 weeks.
      
      16.      Section 171(4) of the Act provides that a woman’s normal weekly earnings are to be taken to be the average weekly earnings
         which in the relevant period have been paid to her.
      
      17.      The Statutory Maternity Pay (General) Regulations 1986, as amended with effect from 12 June 1996 by Statutory Instrument No
         1335 of 1996 (‘the Regulations’), lay down certain conditions for applying the Act with regard to statutory maternity pay.
      
      18.      Regulation 21(2) of the Regulations defines the ‘appropriate date’ as the first date of the 14th week before the expected
         week of confinement, or the first day in the week in which the woman is confined, whichever is earlier.
      
      19.      Regulation 21(3) of the Regulations provides that the relevant period for the purposes of Section 171(4) of the Act is the
         period between:
      
      ‘(a)      the last normal pay day before the appropriate date; and
      (b)      the last normal pay day to fall at least 8 weeks earlier than the normal pay day mentioned in subparagraph (a), including
         the normal pay day mentioned in subparagraph (a) but excluding that first mentioned in subparagraph (b)’.
      
      20.      Regulation 21(7) of the Regulations was inserted by Statutory Instrument No 1335 of 1996 to take account of the Gillespie judgment. It provides as follows:
      
      ‘In any case where a woman receives a backdated pay increase which includes a sum in respect of a relevant period, normal
         weekly earnings shall be calculated as if such sum was paid in that relevant period even though received after that period.’
      
      II –  The main proceedings
      21.      Mrs Michelle K. Alabaster was an employee of Woolwich plc (‘the Woolwich’) in the United Kingdom from 7 December 1987 to 23
         August 1996.
      
      22.      In May 1995 she became pregnant.
      23.      She commenced maternity leave on 8 January 1996. Her expected week of confinement was 11 February 1996 although she gave birth
         on 2 February 1996.
      
      24.      Mrs Alabaster received statutory maternity pay from the week of 8 January 1996. She was paid statutory maternity pay at the
         higher rate not just for the statutory six-week period but for an additional four weeks under her contract of employment.
         She then received statutory maternity pay at the lower rate for eight weeks.
      
      25.      On 12 December 1995 Mrs Alabaster received a salary increase with effect from 1 December. However, this salary increase was
         not reflected in her statutory maternity pay calculation because it came after the relevant period for calculating normal
         earnings.
      
      26.      Pursuant to Regulation 21(3) of the Regulations, the relevant period in Mrs Alabaster’s case began on 1 September 1995 and
         ended on 31 October 1995.
      
      27.      Regulation 21(7) of the Regulations was not applicable in Mrs Alabaster’s case since it only entered into force on 12 June
         1996. In any event, the provision would not have applied because her pay increase was not backdated in respect of the relevant
         period.
      
      28.      On 21 January 1997 Mrs Alabaster brought a complaint against the Woolwich in the Employment Tribunal in the United Kingdom.
         She contended that the failure to reflect the salary increase in her statutory maternity pay calculation constituted discrimination
         against her on grounds of sex contrary to Article 119 of the Treaty.
      
      29.      The Secretary of State for Social Security was joined in the proceedings by an order of the Employment Tribunal dated 30 May
         1997.
      
      30.      By a decision of 10 March 1999 the Employment Tribunal held, applying the Gillespie judgment, that the failure to take account of Mrs Alabaster’s pay increase in determining her statutory maternity pay amounted
         to a breach of Article 119 of the Treaty.
      
      31.      The Woolwich and the Secretary of State for Social Security appealed on this issue to the Employment Appeal Tribunal, which
         dismissed the appeal by a decision of 7 April 2000, also applying Gillespie.
      
      III –  The questions referred for a preliminary ruling
      32.      The respondents in the main proceedings appealed to the Court of Appeal, which decided to stay proceedings and to refer the
         following three questions to the Court of Justice for a preliminary ruling:
      
      ‘In a situation where:
      (a)      the earnings-related element of a woman’s statutory maternity pay (“SMP”) is calculated by reference to her normal weekly
         earnings for an eight week period ending on the 15th week before the expected week of confinement (“the relevant period”),
         and 
      
      (b)      the employer grants a pay rise, which is not back-dated to the relevant period, at any time after the end of the relevant
         period used for calculating that woman’s earnings-related element of SMP and before the end of her maternity leave: 
      
      (1)      Is Article 141 of the EC Treaty and the judgment in Gillespie [1996] ECR I-475 to be interpreted as meaning that the woman is entitled to have that pay rise taken into consideration in
         calculating or re-calculating the earnings-related element of her SMP? 
      
      (2)      Is the answer to Question 1 affected by whether the effective date of the pay rise commences: (i) prior to the beginning of
         the woman’s maternity leave, (ii) prior to the ending of the period of the earnings-related period of her SMP, or (iii) on
         some other date and, if so, on what date? 
      
      (3)      If the answer to Question 1 is in the affirmative, 
      (i)      how should the calculation or re-calculation of the normal weekly earnings in the relevant period take into account the pay
         rise? 
      
      (ii)      Should the relevant period be changed? 
      (iii) What allowance, if any, should be made for other factors occurring within the period to which the pay rise relates such as
         the numbers of hours worked, and the reason for the pay increase? 
      
      (iv)      Does it follow that if there is a reduction in pay after the end of the relevant period but before the end of the woman’s
         period of maternity leave, her SMP should be calculated or re-calculated to take account of the reduction of pay, and if so,
         how is this to be done?’
      
      IV –  First question
      33.      The first question relates to the interpretation of Article 119 of the Treaty and the Gillespie judgment.
      
      34.      The Court of Appeal is asking whether, in the light of that law, a statutory maternity benefit calculated on the basis of
         the woman’s average earnings during a specified period should include pay rises awarded before or during her maternity leave,
         but outside the relevant period prescribed by national law.
      
      35.      The answer to that question depends on the scope to be given to the Gillespie judgment. I shall therefore begin by considering the scope of that judgment (section A below). But I shall also set out the
         difficulties which the Gillespie judgment raises (in section B) and look at how the Court’s case-law on the subject has evolved in this area (section C).
         Those two matters will lead to a consideration of whether a woman’s right to have a pay rise taken account of in her maternity
         pay ought not to be based on Directive 92/85 rather than on the principle of equal treatment (section D).
      
      A –    The scope of the Gillespie judgment
      36.      The facts giving rise to the dispute in Gillespie were analogous to those in this case.
      
      37.      Ms Gillespie and 16 other workers took maternity leave during 1988. In November 1988 they had obtained backdated pay increases
         which took effect on 1 April 1988. However those pay increases had not been included in their maternity benefit as a result
         of the calculation method provided for by the relevant national rules.
      
      38.      The Court of Appeal in Northern Ireland, which was seised of the dispute, referred four questions to the Court for a preliminary
         ruling. It asked, in essence, whether the principle of equal pay required that the plaintiffs continue to receive full pay
         while on maternity leave or, if applicable, that they receive a pay rise awarded before or during their maternity leave.
      
      39.      The Court replied to those questions as follows:
      ‘12      The definition in the second paragraph of Article 119 provides that the concept of pay used in the abovementioned provisions
         includes all consideration which workers receive directly or indirectly from their employers in respect of their employment.
         The legal nature of such consideration is not important for the purposes of the application of Article 119 provided that it
         is granted in respect of employment ... 
      
      13      Consideration classified as pay includes, inter alia, consideration paid by the employer by virtue of legislative provisions and under a contract of employment whose purpose
         is to ensure that workers receive income even where, in certain cases specified by the legislature, they are not performing
         any work provided for in their contracts of employment ... 
      
      14      It follows that, since the benefit paid by an employer under legislation or collective agreements to a woman on maternity
         leave is based on the employment relationship, it constitutes pay within the meaning of Article 119 of the Treaty and Directive
         75/117. 
      
      15      Article 119 of the Treaty and Article 1 of Directive 75/117 therefore preclude regulations which permit men and women to be
         paid at different rates for the same work or for work of equal value. 
      
      16      It is well settled that discrimination involves the application of different rules to comparable situations or the application
         of the same rule to different situations (see, in particular, Case C-279/93 Schumacker [1995] ECR I-225, paragraph 30). 
      
      17      The present case is concerned with women taking maternity leave provided for by national legislation. They are in a special
         position which requires them to be afforded special protection, but which is not comparable either with that of a man or with
         that of a woman actually at work. 
      
      18      As to whether Community law requires women on maternity leave to continue to receive full pay or lays down specific criteria
         determining the amount of benefit payable during maternity leave, Council Directive 92/85 ... provides for various measures
         to protect inter alia the safety and health of female workers, especially before and after giving birth. Those measures include ... rights connected
         with contracts of employment, ..., and maintenance of a payment ..., and/or entitlement to an adequate allowance ... 
      
      19      However, that directive does not apply ratione temporis to the facts of the present case. It was therefore for the national legislature to set the amount of the benefit to be paid
         during maternity leave ... 
      
      20      That being so, it follows that at the material time neither Article 119 of the EEC Treaty nor Article 1 of Directive 75/117
         required that women should continue to receive full pay during maternity leave. Nor did those provisions lay down any specific
         criteria for determining the amount of benefit to be paid to them during that period ... 
      
      21      As to the question whether a woman on maternity leave should receive a pay rise awarded before or during that period, the
         answer must be yes. 
      
      22      The benefit paid during maternity leave is equivalent to a weekly payment calculated on the basis of the average pay received
         by the worker at the time when she was actually working and which was paid to her week by week, just like any other worker.
         The principle of non-discrimination therefore requires that a woman who is still linked to her employer by a contract of employment
         or by an employment relationship during maternity leave must, like any other worker, benefit from any pay rise, even if backdated,
         which is awarded between the beginning of the period covered by reference pay and the end of maternity leave. To deny such
         an increase to a woman on maternity leave would discriminate against her purely in her capacity as a worker since, had she
         not been pregnant, she would have received the pay rise.’
      
      40.      The Court therefore held that the principle of equal pay laid down in Article 119 of the Treaty did not require that women
         should continue to receive full pay during maternity leave nor did it lay down specific criteria for determining the amount
         of maternity benefit payable to them. On other hand, it found that the principle of non-discrimination does require that the
         maternity benefit must include pay rises awarded between the beginning of the relevant period and the end of maternity leave.
      
      41.      The parties in this case hold differing views on the scope of the Gillespie judgment.
      
      42.      The United Kingdom says the judgment must be limited to the circumstances of that case, in other words to situations where
         a pay increase is backdated to the relevant period.
      
      43.      The United Kingdom submits that although the pay increases in Gillespie were decided on before or during the plaintiffs’ maternity leave, they were backdated to the relevant period. In its judgment
         therefore the Court simply found that a pay increase of that kind must be reflected in the amount of maternity benefit. The
         Court did not, however, establish a principle that any pay rise awarded before or during the period of maternity leave but
         outside the relevant period must be reflected in the maternity benefit. In the United Kingdom’s view, such an interpretation
         of Gillespie would create considerable legal uncertainty as well as a whole host of practical difficulties.
      
      44.      Mrs Alabaster challenges that reading of Gillespie. She submits that there is nothing in the judgment to support the claim that the pay rises were backdated to the relevant
         period. In any event she considers that the wording of the Gillespie judgment is clear: the principle of non-discrimination requires that any pay rise awarded before or during maternity leave
         must be taken into account, even if it was awarded outside the relevant period. Mrs Alabaster adds that the practical difficulties
         raised by the United Kingdom cannot call that conclusion in question.
      
      45.      The Commission agrees with Mrs Alabaster’s analysis. It contends that if a Member State opts for a system of maternity pay
         based on a woman’s earnings, that system must comply with Article 119 of the Treaty. This means, following Gillespie, that maternity pay must reflect any pay rises awarded before or during the woman’s maternity leave.
      
      46.      I believe that the scope of the Gillespie judgment is clear. In my view the Court established a principle under which maternity pay calculated on the basis of a woman’s
         earnings during a specified period must reflect any pay rise awarded between the beginning of the relevant period and the
         end of maternity leave.
      
      47.      As Mrs Alabaster said, there is nothing to support the contention that the pay rises in issue in Gillespie were backdated to the relevant period.
      
      48.      The Gillespie judgment merely states that ‘during 1988 the plaintiffs took maternity leave’; (11) that ‘in November 1988, negotiations ... resulted in pay increases being backdated to 1 April 1988’; (12) and that ‘the plaintiffs in the main proceedings were unable to receive that increase’. (13)
      
      49.      Indeed, certain aspects of the Gillespie judgment even suggest that the contested pay rises were backdated to a point in time outside the relevant period.
      
      50.      In paragraph 6 of the judgment the Court stated the reasons why the plaintiffs’ pay rises had not been reflected in their
         maternity benefit to be as follows:
      
      ‘According to the decision of the Industrial Tribunal, referred to in the order for reference, the cash benefit payable during
         maternity leave is determined on the basis of average weekly pay calculated ... from the last two pay cheques received by
         the women concerned for the two months preceding the reference week (“reference pay”). The reference week is defined as the
         15th week before the beginning of the expected week of confinement. No provision was made for an increase in reference pay in the event of a subsequent pay rise.’ (14)
      
      51.      That last sentence therefore appears to suggest that the reason why the plaintiffs did not receive their pay rise was that
         it was awarded outside the reference period laid down by the relevant national rules.
      
      52.      I therefore do not think it has been established that the plaintiffs’ pay rises in Gillespie were backdated to the relevant period.
      
      53.      In any event, the wording of the Gillespie judgment does not to my mind support the view that the Court’s findings are confined to situations where that is the case.
      
      54.      Paragraphs 21 and 22 of the judgment are expressed in terms that are clear and general. Paragraph 21 states: ‘As to the question
         whether a woman on maternity leave should receive a pay rise awarded before or during that period, the answer must be yes.’ Similarly,
         paragraph 22 states that ‘... a woman ... must ... benefit from any pay rise ... which is awarded between the beginning of
         the period covered by reference pay and the end of maternity leave ...’. Finally the operative part of the Gillespie judgment states in clear and general terms as follows:
      
      ‘To the extent that it is calculated on the basis of the pay received by a woman before ... maternity leave, the amount of
         benefit must include pay rises awarded between the beginning of the period covered by the reference pay and the end of maternity
         leave, as from the date on which they take effect.’
      
      55.      It follows that there is nothing to suggest that the principle established in Gillespie  is confined to situations where the pay rise is backdated to the relevant period only.
      
      56.      On the basis of those considerations, the answer to the first question referred for a preliminary ruling must be yes. The
         Court may therefore decide that, under the Gillespie judgment, statutory maternity benefit calculated on the basis of a woman’s average earnings during a specified period must
         include pay rises which are awarded before or during her maternity leave, but outside the relevant period laid down by national
         law.
      
      57.      However, like the United Kingdom, I think that Gillespie raises a number of difficulties. In view of those difficulties, and the way in which the case-law has developed, I propose
         to invite the Court not to uphold the judgment in Gillespie. As we shall see, as Community law currently stands, it is on Directive 92/85, rather than on the principle of equal pay,
         that a woman’s right to have her pay rise taken into account ought to be founded.
      
      B –    The difficulties raised by the Gillespie judgment
      58.      It is well settled that the principle of non-discrimination requires that a woman should not be the subject of unfavourable
         treatment by reason of her pregnancy or because she is on maternity leave. (15) This means that a woman who continues to be bound to her employer during her maternity leave must be able to continue to
         benefit from all working conditions which apply to both men and women. (16)
      
      59.      In Gillespie, (17) the Court inferred from that principle that a woman who is on maternity leave must, like any other worker who is actually
         working, benefit at once from any pay rise, even if it is awarded outside the relevant period or during her maternity leave.
         This requirement means that the pay rise must be reflected in the amount of salary or benefit paid to the woman during her
         maternity leave.
      
      60.      However, the particular feature of the Gillespie judgment is the fact that, in so doing, the Court applied the principle of non-discrimination to a woman on maternity leave
         and, more particularly, to the pay she receives during that time.
      
      61.      It seems to me that this particular application of the principle of equal treatment raises two sets of difficulties.
      62.      First, there is to my mind something of a contradiction between the principle established in Gillespie (18) and paragraphs 16 to 20 of the judgment.
      
      63.      The Court held in paragraphs 16 to 20 of the Gillespie judgment that Article 119 of the Treaty does not apply to women on maternity leave. The reason for that exclusion is that
         the prohibition laid down by Article 119 of the Treaty only applies in cases involving discrimination between men and women,
         whereas the Court takes the view that a woman on maternity leave is in a special situation requiring that she be afforded
         special protection, but which is not comparable with any other situation. The Court thus concluded that Article 119 of the
         Treaty does not require that women continue to receive full pay while on maternity leave, nor does it lay down any criterion
         for determining the amount of maternity benefit.
      
      64.      Yet at the same time the Court held in paragraphs 21 and 22 that the principle of non-discrimination requires that maternity
         benefit calculated on the basis of the pay received by the woman must take account of any pay rise awarded before or during
         her maternity leave. The reason for that requirement is that to do otherwise would be to discriminate against the woman because
         she is pregnant or on maternity leave.
      
      65.      It has to be said that those two principles would seem to be somewhat contradictory. It is difficult to see how the principle
         of non-discrimination, which does not apply during maternity leave and therefore does not posit any criterion for calculating
         maternity benefit, can at the same time impose an obligation to take account of certain pay rises when calculating maternity
         benefit. In other words, it is difficult to comprehend how the principle of non-discrimination, which is not applicable during
         maternity leave, can affect the amount of benefit paid to a woman when she is on maternity leave.
      
      66.      Ultimately, the Gillespie  judgment seems to fall part way between two approaches, which should have been taken to their logical conclusion. The first
         is to exclude application of the principle of non-discrimination during maternity leave. However in that case the principle
         cannot entail an obligation to take account of a pay rise when calculating maternity benefit. The second is to apply the principle
         of non-discrimination to a woman on maternity leave. However in that case Article 119 of the Treaty requires that the woman
         receive her full salary during the whole period of her maternity leave.
      
      67.      Secondly, I believe that the principle laid down in Gillespie could have a detrimental effect on women.
      
      68.      As the Court of Appeal (19) and the United Kingdom (20) pointed out, to apply the principle of non-discrimination to a woman on maternity leave could affect the protection which
         she enjoys during that period.
      
      69.      Under Gillespie, a worker on maternity leave must not be treated any differently from a worker who is actually working. (21) As we have seen, the effect of this is that if the woman is awarded a pay increase before or during her maternity leave,
         that increase must be reflected in the amount of her maternity benefit immediately.
      
      70.      But if the principle of non-discrimination is to be applied correctly, account must also be taken of any adverse matters arising before or during maternity leave. Therefore, if the woman were to suffer a reduction in or loss of earnings
         before or during her maternity leave, the principle of non-discrimination would demand that such reduction or loss too be
         reflected in the amount of her maternity benefit. To do otherwise would be to apply the principle of non-discrimination inconsistently,
         which would be incompatible with the requirements of the principle of legal certainty.
      
      71.      It follows that application of the principle established in Gillespie could have the effect of reducing the amount of benefit paid to women during their maternity leave.
      
      72.      That would be all the more regrettable given that the purpose of the relevant period in the United Kingdom appears to be to
         protect women against any adverse events that occur before or during their maternity leave. The United Kingdom explained that
         this period was chosen so that the woman’s average earnings would be calculated during a period in her pregnancy (between
         the fourth and sixth months) in which as a rule she is subject to few pregnancy-related health problems.
      
      73.      However, as the United Kingdom emphasised, by requiring that all matters that arise prior to maternity leave be taken into
         account, the Gillespie judgment in effect moves the relevant period to the end of the pregnancy, which is the time when women are statistically
         less able to work normally.
      
      74.      Consequently, it is not impossible that the effect of the Gillespie judgment might be to reduce the amount of benefit paid to women during maternity leave. (22)
      
      C –    Evolution of the Court’s case-law
      75.      Furthermore the principle established in Gillespie  appears no longer to be in step with the case-law as it now stands on the protection of rights associated with pregnancy and
         maternity.
      
      76.      Under the current case-law, the Court applies the principles of equal pay and equal treatment outside the period of maternity
         leave only.
      
      77.      Thus the Court has held that the principle of non-discrimination precludes refusing to enter into a contract of employment
         with a female worker on account of her pregnancy; (23) dismissal of a female worker for the same reason; (24) dismissal of a female worker for absences due to incapacity for work caused by illness resulting from her pregnancy; (25) an employer’s refusal to allow a woman to return to work on the ground that she failed to inform her employer that she was
         pregnant before signing the contract of employment; (26) and a rule that deprives a woman of the right to an assessment of her performance because she was absent from the undertaking
         on account of maternity leave. (27)
      
      78.      Similarly, the Court has found that the principle of equal pay precludes an employer, when granting a Christmas bonus, from
         taking a woman’s absence on maternity leave into account so as to reduce the amount thereof. (28) The Court also takes the view that the principle of equal pay demands that a woman continue to receive full pay where she
         is unfit for work before her maternity leave by reason of her pregnancy, if men who are unfit for work have that right. (29)
      
      79.      It is clear that these various different events ─ recruitment, dismissal, return to work, assessment, bonus payments, sick
         leave ─ occur outside the period covered by maternity leave.
      
      80.      However where the woman is on maternity leave the Court no longer applies either the principle of equal pay or the principle
         of equal treatment. It seems on the contrary that it considers the position in the light of the provisions of Directive 92/85
         alone.
      
      81.      Thus the case of Boyle and Others (30) related to a clause in an employment contract which made the payment during the period of maternity leave of pay higher than
         the statutory payment conditional on the worker’s undertaking to return to work after the birth of her child for at least
         one month, failing which she was required to repay the difference between the amount of the pay she received and the amount
         of the statutory payments. The Court took the view that Article 119 of the Treaty did not preclude the application of such
         a clause on the ground that:
      
      ‘... pregnant workers and workers who have recently given birth or who are breastfeeding are in an especially vulnerable situation
         which makes it necessary for the right to maternity leave to be granted to them but which, particularly during that leave,
         cannot be compared to that of a man or a woman on sick leave’. (31)
      
      82.      The Court therefore considered the clause in issue purely in the light of the provisions of Directive 92/85. (32)
      
      83.      Similarly, the case of Høj Pedersen and Others concerned a national rule which provided that a pregnant woman who was unfit for work by reason of a pathological condition
         connected with her pregnancy was not entitled to receive full pay from her employer during the time that she was unfit. It
         was however established that a man who was unfit for work was entitled to receive full pay. The defendants in the main proceedings
         contended by way of justification for that difference that Article 11 of Directive 92/85 authorises the Member States to establish
         a ceiling for the allowances which women may claim in the event of pregnancy. (33)
      
      84.      The Court rejected that argument on the ground that Article 11 of Directive 92/85 only applies to pay or benefits received
         by workers in the context of maternity leave. (34) Since the dispute in that case concerned incapacity for work before maternity leave, the Court held that Article 119 of the Treaty required that a woman too continue to receive full pay if
         she is unfit for work. (35)
      
      85.      Finally, in the Lewen case (36) the Court held that a Christmas bonus paid voluntarily by the employer as an incentive for future work cannot constitute
         pay within the meaning of Article 11(2)(b) of Directive 92/85 in so far as it is not intended to ensure that, during her maternity
         leave, the worker receives an adequate level of income.
      
      86.      It follows from those judgments that, since the entry into force of Directive 92/85, the Court has drawn a distinction between
         two separate periods. The first covers pregnancy up to the beginning of maternity leave, and the second covers the period
         of maternity leave. The Court applies Article 119 of the Treaty and the principle of equal treatment during the first period
         only. When the woman is on maternity leave, however, her position is considered in the light of the provisions of Directive
         92/85 alone. That means that if the woman suffers unfavourable treatment during her maternity leave, such treatment is only
         prohibited if it is contrary to the provisions of Directive 92/85. (37)
      
      87.      On that basis, it seems to me that the principle established in Gillespie  no longer accords with current case-law. As I have said, in that case the Court applied the principle of non-discrimination
         to the second period referred to above and, more particularly, to the woman’s pay during maternity leave.
      
      88.      Having regard to the difficulties set out above and the way in which the case-law has evolved, I would suggest that the Court
         ought not to uphold the principle established in Gillespie. A woman’s entitlement to benefit from a pay rise ought to my mind now to be founded on Directive 92/85.
      
      D –    The basis of the woman’s right
      89.      As we have seen, Directive 92/85 was adopted on the basis of Article 118a of the Treaty to confer special protection on workers
         during pregnancy and maternity leave. The Community legislature took the view that pregnant workers, workers who have recently
         given birth and workers who are breastfeeding are in many respects a specific risk group and that measures ought to be taken
         to ensure their safety and health. (38) It thus adopted a range of protective measures, such as the prohibition on dismissing women during pregnancy and maternity
         leave, and time off for antenatal appointments.
      
      90.      As part of those measures, Directive 92/85 provides that women must be entitled to a continuous period of maternity leave
         of at least 14 weeks, including compulsory maternity leave of at least 2 weeks. In addition Article 11(2) of Directive 92/85
         provides that during maternity leave the following must be ensured:
      
      ‘(a)      the rights connected with the employment contract of workers ... other than those referred to in point (b) below; 
      (b)      maintenance of a payment ..., and/or entitlement to an adequate allowance ...’. 
      91.      It seems to me that subparagraph (a) could be interpreted as covering pay rises awarded before or during maternity leave.
         A worker’s entitlement to benefit immediately from a pay rise awarded to her may be regarded as a ‘right connected with [her]
         employment contract’. (39)
      
      92.      That interpretation would enable the difficulties identified above to be avoided.
      93.      First, it would be consistent with the principle that women on maternity leave are in a special position which requires them
         to be afforded special protection but which is not comparable with any other situation. (40) The proposed interpretation would involve applying to a woman on maternity leave the measures adopted specifically to ensure
         that she is protected. It would further guarantee that any pay rises are included in her maternity pay without having to compare
         her situation with that of a woman who is actually working. (41)
      
      94.      Furthermore it seems to me that the application of Directive 92/85 would enable certain adverse events that occur during maternity
         leave to be excluded. (42)
      
      95.      It will be recalled that the purpose of Directive 92/85 is to ensure that women are afforded special protection during their
         maternity leave. In addition, Article 1(3) of the Directive contains the idea that application of the Directive may not have
         the effect of reducing the level of protection afforded to pregnant workers, workers who have recently given birth or who
         are breastfeeding. It could be argued on the basis of those two elements that a woman could not, while she is on maternity
         leave, suffer any reduction in or loss of earnings.
      
      96.      That view is supported by the wording of Article 11(2)(a) of Directive 92/85. Whilst immediate entitlement to the benefit
         of a pay rise awarded while a woman is on maternity leave can amount to a ‘right’ connected with her contract of employment,
         it is difficult to argue that an obligation to reflect any reduction in or loss of earnings in the amount of maternity benefit
         constitutes such a ‘right’. In other words the concept of ‘rights connected with the employment contract’ would require that
         account be taken of pay rises awarded before or during maternity leave, but not of reductions in or losses of earnings suffered
         during maternity leave. Such reductions or losses could occur only after the end of the woman’s maternity leave. 
      
      97.      Finally the interpretation I have proposed is consistent with the current case-law on the protection of rights arising in
         connection with pregnancy and maternity. (43) It entails applying only the provisions of Directive 92/85 to women on maternity leave and in particular to their pay while
         on maternity leave.
      
      98.      Consequently I am of the view that the law on female workers may henceforth be founded on the provisions of Article 11(2)(a)
         of Directive 92/85.
      
      99.      I therefore propose that the Court reply to the first question referred for a preliminary ruling that Article 119 of the Treaty
         and the principle of non-discrimination do not require that statutory maternity pay calculated on the basis of a woman’s average
         earnings during a specified period take account of pay rises awarded before or during maternity leave, but outside the reference
         period. Rather, the obligation to reflect such pay rises in the amount of maternity pay arises under Article 11(2)(a) of Directive
         92/85.
      
      V –  Second question
      100. By its second question the Court of Appeal is asking whether the fact that a pay rise takes effect before the beginning of
         maternity leave, before the end of the period of payment of the earnings-related element of maternity pay or, if appropriate,
         on some other date, has any effect on the reply to the first question.
      
      101. The considerations set out in the analysis of the first question enable a reply to be given the national court. It is clear
         that, regardless of the legal basis used, the amount of the earnings-related element of the woman’s statutory maternity pay
         must take account of any pay rise awarded between the start of the relevant period and the end of maternity leave.
      
      VI –  Third question
      102. The last question to be referred for a preliminary ruling divides into four parts which I shall consider in turn.
      103. The first two parts relate to the detailed rules for applying the principle established in Gillespie. The national court is asking how a pay rise is to be taken into account in calculating the woman’s normal earnings during
         the relevant period. It also wishes to know whether the relevant period prescribed by national law ought to be changed.
      
      104. Those questions are clearly of fundamental significance to employers in the United Kingdom. Following the judgment in this
         case they will have to calculate or review maternity pay in relation to all women awarded a pay rise before or during their
         maternity leave. Having regard to the large number of possible scenarios and difficulties, the national court and the defendant
         in the main proceedings (44) seek detailed guidance on how to do this.
      
      105. However it seems to me that those questions can only be dealt with applying the principle of procedural autonomy. (45) In the absence of any Community legislation in this area, it is for the legal system of each Member State to lay down the
         detailed rules for applying the judgment delivered in this case, including any immediate implementing measures.
      
      106. The second two parts of the question relate to the possible consequences of Gillespie  in the event that the judgment requires that maternity pay take account of pay rises awarded before or during maternity leave
         but outside the relevant period. The Court of Appeal is asking whether Article 119 of the Treaty requires that, if it does,
         other factors occurring before or during maternity leave must be taken into account, in particular any loss of or reduction
         in earnings.
      
      107. As we have seen, this question, though merely theoretical in the present case, is most apposite. Logical application of the
         principle established in Gillespie demands that statutory maternity pay include not only pay rises awarded before or during maternity leave but also reductions
         in and losses of earnings suffered during that period. (46) We have, however, seen how some of those adverse consequences may be obviated by using Directive 92/85. (47)
      
      VII –  Conclusion
      108. On the basis of the foregoing considerations I therefore propose that the Court reply to the questions referred to the Court
         for a preliminary ruling by the Court of Appeal of England and Wales, Civil Division, as follows:
      
      (1)      Article 119 of the EC Treaty (Articles 117 to 120 of the EC Treaty have been replaced by Articles 136 EC to 143 EC) on the
         principle of non-discrimination must be interpreted as meaning that, where statutory maternity benefit is calculated on the
         basis of a worker’s average earnings during a specified period, that benefit need not include any pay rises awarded before
         or during the worker’s period of maternity leave, but outside the relevant period laid down by national law.
      
      (2)      However, Article 11(2)(a) of Council Directive 92/85/EEC of 19 October 1992 on the introduction of measures to encourage improvements
         in the safety and health at work of pregnant workers and workers who have recently given birth or are breastfeeding (tenth
         individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC) requires that where statutory maternity
         benefit is calculated on the basis of the worker’s average earnings during a specified period, that benefit must include any
         pay rises awarded before or during the worker’s period of maternity leave. 
      
      (3)      In the absence of any Community legislation in this sphere it is for each Member State to determine the detailed rules according
         to which the pay rises referred to in paragraph 2 are to be taken into account in the amount of the woman’s statutory maternity
         pay.

      21 –	See the Gillespie judgment, paragraph 22.
      
      22 –	The United Kingdom noted a further negative consequence of the Gillespie judgment. It pointed out that under Directive 92/85, the Member States are free, with regard to women’s earnings during their
         maternity leave, to choose between paying a proportion of the woman’s earnings and paying a flat-rate benefit (such as EUR
         50 per week). It also explained that in the United Kingdom it is the employer who has the responsibility for calculating the
         amount of maternity benefit and that more than 70% of employers are small- or medium-sized enterprises, so that it is unlikely
         that they have the necessary resources to make frequent, complex calculations. In view of those factors, the United Kingdom
         indicated that the principle established in Gillespie created an ‘administrative nightmare for employers’ since it requires them to take account of all increases in pay awarded
         before or during maternity leave regardless of the amount. The United Kingdom therefore explained that the Gillespie judgment could cause certain Member States to abandon an earnings-related regime in favour of a flat-rate benefit one. I
         believe that the risk of provoking such change is real given the pressure which employers are one way or another able to exert
         on the competent authorities. Furthermore, a change of this order would be detrimental to women because the flat-rate regime
         is in most cases more unjust than the earnings-related one. However to my mind, it is not certain that Member States are entitled
         to make such a change. Article 1(3) of Directive 92/85 states expressly: ‘This Directive may not have the effect of reducing
         the level of protection afforded to pregnant workers, workers who have recently given birth or who are breastfeeding compared
         with the situation which exists in each Member State on the date on which this Directive is adopted’. The provision could
         therefore preclude the Member States invoking the freedom accorded by Directive 92/85 to justify a change of regime entailing
         a reduction in the protection which women enjoy during their maternity leave in the Member State concerned.

      39 –	However it seems harder to found the woman’s rights on Article 11(2)(b) of Directive 92/85. The purpose of those provisions
         is to ensure an ‘adequate’ level of income for women on maternity leave (see on this point Boyle paragraphs 33 and 34 and Lewen  paragraphs 22 and 23). Therefore if the authorities or persons concerned are paying adequate remuneration and/or benefits,
         they are implementing Article 11(2)(b) of Directive 92/85 correctly. That provision does not require that in addition they
         reflect any pay rises awarded to the woman in her maternity pay.
