Summarize the following court judgment. Special Leave Petition No. 416 of 1981. From the judgment and order dated the 5th September	 1980 of the Punjab and Haryana High Court in Civil Writ Petition No. 1515 of 1980. L.N. Sinha	 Attorney General	 K.S. Gurumoorthy & R.N. Poddar for the Petitioner. The Order of the Court was delivered by PATHAK	 J. This petition for special leave to appeal by the Union of India is directed against the judgment and order of the High Court of Punjab and Haryana holding the respondent	 a retired Judge of the High Court	 entitled to the payment of the cash equivalent of leave salary in respect of the period of earned leave at his credit on the date of his retirement. The respondent	 Shri Gurnam Singh	 was a member of the Superior Judicial Service in the State of Haryana. On February 24	 1972 he was appointed a Judge of the High Court of Punjab and Haryana and retired on March 18	 1980 on attaining the age of 62 years. On the date of retirement the respondent had to his credit earned leave which had not been availed of by him. He claimed that he was entitled to receive the cash equivalent of leave salary in respect of the period of unutilised earned leave. He also claimed dearness allowance for the period before retirement. The claim being denied	 the respondent applied to the High Court of Punjab and Haryana for relief under Article 226 of the Constitution. The 702 writ petition was allowed by the High Court by its judgment and order dated September 5	 1980 and a direction was issued to the Union of India to pay the amount claimed. During the course of the hearing the Union of India conceded the claim to dearness allowance in view of the order dated July 3	 1980 of the Government that the Judges of the High Court were entitled to draw dearness allowance from December 1	 1979. As to the remaining claim	 the High Court held the respondent entitled to the cash equivalent of the leave salary for the period of unutilised earned leave by giving him the benefit of rule 20 B	 All India Services (Leave) Rules	 1955 by virtue of rule 2 of the High Court Judges Rules	 1956. The order of the High Court is assailed before us. In our opinion	 the High Court is plainly right. Article 221 of the Constitution provides for the payment of salaries and allowances to a Judge of a High Court. Clause (2) of Article 221 declares: "(2) Every Judge shall be entitled to such allowances and to such rights in respect of leave of absence and pension as may from time to time be determined by or under law made by Parliament and	 until so determined	 to such allowances and rights as are specified in the Second Schedule: . . " The rights in respect of leave of absence to which a Judge is entitled may be determined by or under law made by Parliament. Parliament enacted the 	 and sections 3 to 13 of that Act classify the kinds of leave admissible to a Judge	 and provide for the maintenance of a leave account	 the aggregate amount of leave which may be granted	 the commutation of leave on half allowance into leave on full allowance	 the grant of leave not due	 special disability leave	 extraordinary leave	 the rate of leave allowances	 allowance for joining time	 for combining leave with vacation and the consequences of overstaying leave or vacation	 It also specifies the authority competent to grant leave. The Union of India says that these several provisions constitute a complete code and exhaustively set forth all the benefits relating to leave to which a Judge of a High Court is entitled	 and that it is not permissible to proceed beyond those provisions to discover any further right in favour of a Judge. That submission is inadmissible. Sub section (1) of section 24 of the same Act empowers of 703 Central Government to make rules to carry out the purpose of the Act. And clause (a) of Sub section (2) of section 24 specifically contemplates rules providing for "leave of absence of a Judge". In other words	 it is open to the Central Government to add to the existing statutory provisions by making rules in relation to leave of absence. Sub section (2) of section 24 in fact enables the Central Government to make rules in respect of several other matters	 such as the pension payable to a Judge	 travelling allowances	 use of official residence	 facilities for medical treatment and other conditions of service and "any other matter which has to be	 or may be prescribed". Now the Government of India enacted the High Court Judges Rules	 1956 and rule 2 comprehensively declares: "2. The conditions of services of a Judge of a High Court for which no express provision has been made in the 	 shall be	 and shall from the commencement of the Constitution be deemed to have been	 determined by the rules for the time being applicable to a member of the Indian Administrative Service holding the rank of Secretary to the Government of the State in which the principal seat of the High Court is situated. Provided that	 in the case of a Judge of the High Court of Delhi and a Judge of the High Court of Punjab and Haryana the conditions of service shall be determined by the rules for the time being applicable to a member of the Indian Administrative Service on deputation to the Government of India holding the rank of Joint Secretary to the Government of India stationed at New Delhi. Provided further that in respect of facilities for medical treatment and accommodation in hospitals the provisions of the All India Service (Medical Attendance) Rules	 1954	 in their application to a Judge	 shall be deemed to have taken effect from the 26th January	 1950. Provided also that where at the request of the President	 any Judge undertakes to discharge any function outside his normal duties in any locality away from of his headquarters	 the President may	 having regard to the nature of such function and locality	 determine the facilities that may be afforded to such judge including accommodation	 transport and telephone so long as he continues to dis 704 charge such function	 either without any payment or at a concessional rate." Rule 2A sets forth the rights of a Judge who avails of an official residence and Rule 2B provides the scale of its free furnishing. It is clear from Rule 2 of the High Court Judges Rules	 1956	 that the conditions of service of a Judge of the High Court of Punjab and Haryana	 where not expressly provided in the must be determined by the rules governing a member of the Indian Administrative Service of the rank of Joint Secretary to the Government of India stationed at New Delhi. The All India Services (Leave) Rules	 1955 contain provision for leave in relation to members of the All India Services	 including the Indian Administrative Service. On the date when the respondent retired those rules included rule 20 B which provides: "20 B. Payment of cash equivalent of leave salary: (1) The Government shall suo moto sanction to a member of the service who retires from the service under sub rule (1) of rule 16 of the All India Services (Death cum Retirement Benefits) Rules	 1958	 having attained the age of 58 years on or after the 30th September	 1977 the cash equivalent of leave salary in respect of the period of earned leave at his credit on the date of his retirement	 subject to a maximum of 180 days. (2) The cash equivalent of leave salary payable to a member of the Service under sub rule (1) above shall also include dearness allowance admissible to him on the leave salary at the rates in force on the date of retirement	 and it shall be paid in one lump sum	 as a one time settlement. (3) The city compensatory allowance and the house rent allowance shall not be included in calculating the cash equivalent of leave salary under this rule. (4) From the cash equivalent so worked out no deduction shall be made on account of pension and pensionary equivalent of other retirement benefits. 705 It is not disputed that Rule 20 B applies to a member of the Indian Administrative Service of the rank of Joint Secretary to the Government of India stationed at New Delhi. The rule entitles him on retirement from service to the cash equivalent of leave salary in respect of the period of unutilised earned leave subject to a maximum of 180 days	 inclusive of dearness allowance. It is apparent that by virtue of Rule 2 of the High Court Judges Rules	 1956 this benefit must be read as a condition of service enjoyed by a Judge of the High Court. It may be observed that although rule 20 B of the All India Services (Leave) Rules	 1955 is a provision of a scheme applicable to members of the All India Services	 there is nothing in its nature and content which makes it inapplicable mutatis mutandis to the statutory scheme pertaining to leave enacted in the . There is also nothing in the constitutional position of a Judge of a High Court which precludes Rule 20 B from inclusion in that scheme. It is true that Rule 20 B revolves around the concept of earned leave	 and the expression "earned leave" has been specifically defined by clause (d) of rule 2 of the All India Services (Leave) Rules	 1955 as "leave earned under rule 10". But rule 10 merely lays down the rate and amount of earned leave. The principle in which "earned leave" is rooted must be discovered from rule 4	 which provides that "except as otherwise provided in these rules leave shall be earned by duty only". The performance of duty is the basis of earning leave. That concept is also embedded in the . Under that Act	 the time spent by a Judge on duty constitutes the primary ingredient in the concept of "actual service"	(1) which is the reason for crediting leave in the leave account of a Judge.(2) Although the expression "earned leave" is not employed in the Act	 the fundamental premise for the grant of leave to a Judge is that he has earned it. He has earned it by virtue of the time spent by him on actual service. That a Judge earns the leave which is credited to his leave account is borne out by the proviso to section 6 of the Act	 which declares that the grant under section 6 of leave not due will not be mad "if the Judge is not expected to return to duty at the end of such leave and earn the leave granted" (emphasis provided). The concept then on which rule 20 B proceeds is familiar to and underlies the statutory scheme relating to leave formulated in the Act. It bears a logical and reasonable relationship to the essential content of that scheme. On 706 that	 it must be regarded as a provision absorbed by rule 2 of the High Court Judges Rules	 1956 into the statutory structure defining the conditions of service of a Judge of a High Court. We may observe that even as a right to receive pension	 although accruing on retirement	 is a condition of service	 so also the right to the payment of the cash equivalent of leave salary for the period of unutilised leave accruing on the date of retirement must be considered as a condition of service. In our judgment	 the High Court is right in upholding the claim of the respondent to the payment of the cash equivalent of the leave salary in respect of the period of earned leave at his credit on the date of retirement in accordance with the provisions of rule 20 B of the All India Services (Leave) Rules	 1955 read with rule 2 of the High Court Judges Rules	 1956. The Special Leave petition is dismissed. P.B.R. Petition dismissed.

On his retirement as Judge of the Punjab and Haryana High Court the respondent claimed cash equivalent of leave salary in respect of the unutilised earned leave standing to his credit. His claim was rejected by the Government. Allowing his petition under Article 226 of the Constitution the High Court directed the Government to pay the leave salary claimed by him. In its petition for grant of special leave the appellant contended that the being a complete code governing the conditions of service of High Court Judges it would not be permissible to proceed beyond those provisions to discover any further rights in favour of the Judges of the High Court. Dismissing the petition	 ^ HELD : The High Court was right in upholding the respondent 's claim for payment of the cash equivalent of leave salary in respect of the period of unutilised earned leave at the credit of the Judge on the date of his retirement in accordance with the provisions of rule 20B of the All India Services (Leave) Rules 1955 read with rule 2 of the High Court Judges Rules 1956. [706 B C] Section 24(2)(a) of the 1954 Act enables the Central Government to make rules in respect of	 among others	 "any other matter which has to be or could be prescribed." [703 B] The second proviso to rule 2 of the High Court Judges ' Rules	 1956 provides that	 in the case of a Judge of the High Court of Punjab and Haryana	 if no provision had been expressly made in the 1954 Act	 as to the conditions of his service	 they shall be determined by the rules applicable to a member of the Indian Administrative Service of the rank of Joint Secretary to the Government of India stationed at New Delhi. Rule 20B of All India Services (Leave) Rules 1955	 which is the rule applicable to a member of the Indian Administrative Service of the rank of Joint Secretary to the Government of India stationed at New Delhi	 entitles him on retirement from service to the cash equivalent of leave salary in respect of the period of unutilised earned leave subject to a maximum of 180 days. By virtue of rule 2 of the High Court Judges Rules 1956 this 701 benefit must be read as a condition of service enjoyed by a Judge of the High Court. [704 B C	 705 A B] The concept of "earned leave" is embedded in the 1954 Act under which the time spent by a Judge on duty constitutes the primary ingredient in the concept of "actual service" which is the reason for crediting leave in the leave account of a Judge. Although the expression "earned leave" is not employed in the 1954 Act the fundamental premise for grant of leave to a Judge is that he has earned it. That a Judge earns the leave which is credited to his leave account is borne out by the proviso to section 6 of the 1954 Act. The concept on which rule 20B proceeds is familiar to and underlies the statutory scheme relating to leave formulated in the Act. It bears a logical and reasonable relationship to the essential content of that scheme. On that it must be regarded as a provision absorbed by rule 2 of the High Court Judges ' Rules 1956 into the statutory structure defining the conditions of service of a Judge of the High Court.
