SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-543/23 
 
2  
Questions referred for a preliminary ruling 
‘1. Must clause 4(1) of the framework agreement on fixed-term work concluded 
on 18 March 1999 annexed to Council Directive 1999/70/EC of 28 June 1999 and 
the general principle under [EU] law as it currently stands of non-discrimination 
in the area of employment conditions, read in the light of Article 21 of the Charter 
of Fundamental Rights of the European Union (‘the Charter’), be interpreted as 
precluding national legislation, such as that contained in Article 485 of Decreto 
legislativo n. 297/94 (Legislative Decree No 297/94), which, according to the 
interpretation given by the Suprema Corte di Cassazione (Supreme Court of 
Cassation, Italy) (see Cass. S.L. judgments No 32386/2019, No 33134/2019 and 
No 33137 of 2019), provides that the fixed-term employees of scuole paritarie 
(State-equivalent schools) referred to in Legge n. 62/2000 (Law No 62/2000) are 
to be treated less favourably, when assessing what rights they have accrued 
during their career, than permanent employees of the Ministero dell’Istruzione e 
del Merito (Ministry of Education and Merit, Italy), solely due to the fact that they 
have not passed a public selection process or have taught as an employee of a 
legally recognised scuola paritaria (State-equivalent school), notwithstanding the 
fact that fixed-term teaching staff at scuole paritarie (State-equivalent schools) are 
in a situation comparable to that of permanent teaching staff at State schools, 
with regard to the type of work and training and employment conditions, in so far 
as they perform the same tasks, have the same disciplinary, pedagogic, 
methodological-didactic, organisational-relational and research skills, gained 
through teaching experience, as acknowledged by that national law as being 
identical for the purposes of recruitment under a contract of indefinite duration by 
referring to the permanent ranking lists, which are now closed (see Article 2(2) of 
Decreto-legge n. 255/2001 (Decree-law No 255/2001))? 
2. In the context of the application of Directive 1999/70, must the general 
principles under [EU] law as it currently stands of equality, equal treatment and 
non-discrimination in the area of employment, as also enshrined in Articles 20 
and 21 of the Charter, in Article 14 of the European Convention on Human Rights 
(which is relevant pursuant to Article 52 of the Charter), in the European Social 
Charter approved on 18 June 1961, in Article 157 TFEU and in Directives 
2000/43/EC and 2000/78/EC, be interpreted as precluding legislation, such as 
that contained in Article 485 of Legislative Decree No 297/94, which stipulates 
that only the teaching services of an employee of the Ministry or of a scuola 
parificata (State-accredited primary school), a scuola pareggiata (State-equivalent 
secondary school), a scuola sussidiata o sussidiaria (small State-funded school run 
by private individuals or entities), a scuola popolare (school for adult education) 
or an educandato (girls’ school run by a religious body) are to be taken into 
account for salary purposes, when assessing what rights have been accrued 
during a career, thereby treating fixed-term teaching staff at scuole paritarie 
(State-equivalent schools) less favourably and discriminating against them when 
assessing what rights they have accrued during their career (such assessment 
being carried out after recruitment under a contract of indefinite duration by the 
Ministry of Education and Merit), failing to acknowledge their right to the

supplementary pay connected with length of service, which is, however, paid to 
fixed-term teaching staff at State and municipal schools, scuole parificate (State-
accredited primary schools), scuole pareggiate (State-equivalent secondary 
schools), scuole sussidiate e sussidiarie (small State-funded schools run by private 
individuals or entities), and scuole popolari (schools for adult education) and 
educandati (girls’ schools run by religious bodies), who are in a situation 
comparable with that of teaching staff at scuole paritarie (State-equivalent 
schools) with regard to the type of work, duties, services and professional 
obligations, as well as the training and working conditions with respect to the 
teaching staff at the scuole paritarie (State-equivalent schools) referred to in Law 
No 62/2000, in so far as they perform the same tasks and gain, through the 
teaching experience they acquire, the same disciplinary, pedagogic, 
methodological-didactic, organisational-relational and research skills as teaching 
staff at scuole paritarie (State-equivalent schools)? 
3. Must the concept of ‘comparable permanent worker’ referred to in clause 
4(1) of the framework agreement on fixed-term work concluded on 18 March 
1999, annexed to Directive 1999/70, and the general principles under EU law as 
it currently stands of equality, equal treatment and non-discrimination in the area 
of employment, enshrined in Articles 20 and 21 of the Charter, be interpreted as 
meaning that, in the context of the recognition of years of service accrued, the 
services provided as a temporary employee in scuole paritarie (State-equivalent 
schools) must be treated in the same way as those provided in State schools, 
scuole parificate (State-accredited primary schools), scuole pareggiate (State-
equivalent secondary schools), scuole popolari (schools for adult education), 
scuole sussidiate e sussidiarie (small State-funded schools run by private 
individuals or entities), and educandati (girls’ schools run by religious bodies), in 
so far as those teachers perform the same tasks, have the same professional 
obligations and possess the same disciplinary, pedagogic, methodological-
didactic, organisational-relational and research skills? 
4. If Article 485 of Legislative Decree No 297/94 is incompatible with the [EU] 
law, does the Charter oblige the national court to disapply the incompatible piece 
of national legislation?’ 
Provisions of European Union law and principal case-law relied on 
Clause 4 of the ETUC-UNICE-CEEP framework agreement on fixed-term work, 
concluded on 18 March 1999, annexed to Council Directive 1999/70/EC of 
28 June 1999 (‘the framework agreement on fixed-term work’) 
Articles 20 and 21 of the Charter of Fundamental Rights of the European Union 
(‘the Charter’) (general principles of equality, equal treatment and non-
discrimination in the area of employment conditions)

Succinct presentation of the facts and procedure in the main proceedings 
1 The applicant was employed at a scuola paritaria (State-equivalent school) under 
five fixed-term contracts entered into from the academic year 2002/2003 up to 
31 August 2007. 
2 On 1 September 2008, he was recruited as a permanent member of staff by the 
Ministero dell’Istruzione (Ministry of Education), via a closed ranking list. When 
his salary level was assessed, the years he had worked in the scuola paritaria 
(State-equivalent school) were not taken into account when calculating his length 
of service, since Article 485 of Legislative Decree No 297/94 states that, for the 
purpose of assessing what rights he had accrued and of determining his initial 
salary band, only those services completed in State schools and in scuole 
parificate (State-accredited primary schools), scuole pareggiate (State-equivalent 
secondary schools), scuole sussidiarie e sussidiate (small State-funded schools run 
by private individuals or entities), scuole popolari (schools for adult education) 
and educandati (girls’ schools run by religious bodies) are to be taken into 
account. 
3 The applicant argues, before the referring court, that Legislative Decree 
No 297/94 is inconsistent with clause 4 of the framework agreement on fixed-term 
work and Articles 20 and 21 of the Charter on the basis that it is allegedly 
discriminatory and entails an unjustified inequality of treatment. 
SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-543/23 
 
6  
The essential arguments of the parties in the main proceedings 
4 The applicant claims that he is entitled to have the period of service between 2002 
and 2007 taken into account in so far as he taught in the scuola paritaria (State-
equivalent school) from 16 September 2002, that is to say at a time when, 
according to Law No 62/2000, scuole parificate (State-accredited primary 
schools) and scuole pareggiate (State-equivalent secondary schools) had been 
merged into the single category of scuole paritarie (State-equivalent schools), 
which the legislator considered to be comparable with each other and with State 
schools. The reference contained in Article 485 of Legislative Decree No 297/94 
to periods of service as an employee of scuole parificate (State-accredited primary 
schools) and scuole pareggiate (State-equivalent secondary schools) – which had 
by then been abolished – being taken into account should therefore apply to 
schools now referred to as scuole paritarie (State-equivalent schools). 
5 According to the applicant, Article 2 of the subsequent Legislative Decree 
No 255/2001 attests to the fact that Article 485 of Legislative Decree No 297/94 is 
‘obsolete’. The failure to update Article 485 of Legislative Decree No 297/94 in 
fact means that teaching services provided in scuole paritarie (State-equivalent 
schools) are to be considered to be identical to services provided by fixed-term 
employees in State schools for the purpose of recruitment under a contract of 
indefinite duration (without a public selection process) by the Ministry of 
Education, but are in no way comparable, on the other hand, when assessing the 
salary band at the time that employee is awarded a permanent contract by the 
Ministry of Education. 
6 However, according to the applicant, in order to teach at a scuola paritaria (State-
equivalent school), the employee requires additional qualifications as compared 
with employees at State schools or the other schools referred to in Legislative 
Decree No 297/94, in so far as, in order to teach on a fixed-term basis at what are 
now referred to as scuole paritarie (State-equivalent schools), on the basis of 
Article 1(4) of Law No 62/2000, it is essential that a teacher also hold a 
qualification as a teacher, whilst a teacher recruited on a fixed-term basis at State 
schools or in a private scuola parificata (State-accredited primary school), scuola 
sussidiaria o sussidiata (small State-funded school run by private individuals or 
entities) or scuola popolare (school for adult education) need only be in 
possession of a secondary school diploma. The increased knowledge and 
professional skills of the teacher, which justifies that teacher receiving the 
additional years of service in question, is therefore all the more relevant for the 
teaching staff of a scuola paritaria (State-equivalent school), who are nevertheless 
unable to reap the benefit of that knowledge and those skills, even in part. 
7 The Ministry of Education does not contest the fact that the services provided by 
teaching staff at scuole paritarie (State-equivalent schools) are identical to those 
provided in State schools and the other categories of school mentioned. However, 
it argues that Article 485 of Legislative Decree No 297/94 has not been brought 
into line with Law No 62/2000; for the purpose of the former it is still the case 
GNATTAI 
 
7 
that only services provided when employed at a scuola parificata (State-
accredited primary school) or a scuola pareggiata (State-equivalent secondary 
school) are to be taken into account, whilst services provided at the new scuole 
paritarie (State-equivalent schools) – a category created only in 2000 and which 
subsumed scuole parificate (State-accredited primary schools) and scuole 
pareggiate (State-equivalent secondary schools) – are not to be taken into account. 
That absence of correlation does not make it possible, as the law currently stands, 
to accrue years of service at a scuola paritaria (State-equivalent school) for 
services performed before becoming a permanent member of staff, as compared 
with teaching staff who have provided the same service (and therefore gained the 
same working experience) but have immediately been awarded permanent 
contracts at State schools, having passed a public selection process, or fixed-term 
contracts in former scuole parificate (State-accredited primary schools) or scuole 
pareggiate (State-equivalent secondary schools) or in scuole sussidiarie e 
sussidiate (small State-funded schools run by private individuals or entities), 
scuole popolari (schools for adult education) or educandati (girls’ schools run by 
religious bodies). 
Succinct presentation of the reasoning in the request for a preliminary ruling 
8 The Supreme Court of Cassation acknowledged that a scuola paritaria (State-
equivalent school) is treated in every sense as a State school, yet it is nevertheless 
not to be taken into account, according to its interpretation of Article 485 of 
Legislative Decree No 297/94, when calculating what services had been provided 
before the grant of a permanent contract, on the ground that the dissimilar 
recruitment procedures make it clear that the legal status of the respective teachers 
is not the same (Cass. No 32386/2019, Cass. No 33137/2019 and Cass. 
No 33134/2019). 
Moreover, the Court did not find any breach of the principle of non-discrimination 
provided for in clause 4 of the framework agreement on fixed-term work, 
‘because relationships are not comparable where they arise in the context of 
different employers and where they are subject to different regulations with regard 
to the establishment and management of those relationships’ (Cass. n. 
25226/2020). The Corte Costituzionale (Constitutional Court, Italy) has also made 
findings to the same effect (Corte Cost. n. 18/2001). 
9 The Court of Justice has observed previously that the prohibition of 
discrimination, provided for in clause 4 of the framework agreement on fixed-term 
work, proscribes any unequal treatment of fixed-term workers that is not justified 
on objective grounds by precise, concrete distinguishing factors relating to the 
inherent characteristics of the tasks and duties performed. 
The issue therefore arises as to whether Article 485 of Legislative Decree 
No 297/94, as interpreted by the Supreme Court of Cassation, is consistent with 
EU law, in so far as it is evident in the present case that there is no difference 
SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-543/23 
 
8  
between the duties, training, services and professional obligations of a permanent 
member of the teaching staff at a State school and those of a teacher on a fixed-
term contract at a scuola paritaria (State-equivalent school), as in the case of the 
applicant. 
10 In fact, the Ministry of Education does not dispute the fact that the teaching 
services provided by the applicant, as part of a fixed-term working relationship at 
the scuola paritaria (State-equivalent school) in question, involved tasks and 
contractual obligations that were identical to those provided by his equivalents 
working as permanent members of staff at State schools. 
11 This also rules out the conclusion that the situations being assessed are 
incomparable, in so far as it is the same Italian legislator that acknowledges the 
equivalence of the services provided by teaching staff at scuole paritarie (State-
equivalent schools), under Article 1 of Law No 62/2000, with regard not only to 
the academic qualification awarded, but also the quality of the teaching service 
provided, and the absolute relevance of the experience accrued in those schools 
for the purposes of entering or moving forward in permanent ranking lists 
(Article 2 of Legislative Decree No 255/2001). 
12 The private nature of the previous employer, with which the teaching experience 
was accrued, is equally irrelevant. If the superior professional skills resulting from 
length of service, which justifies the accrual of years of service in question, had 
something to do with the legal status of the employer, namely it being a State or 
public employer – for example if Article 485 of Legislative Decree No 297/94 had 
aimed at securing the loyalty of employees of the Ministry of Education, 
Universities and Research or at attaching importance to the distinctive features of 
the State school sector – the regulation would have taken into consideration only 
services provided when employed by the Ministry or at a State school. 
13 In the same way, the alleged requirement that only the services provided by those 
who have been successful in a public selection process be taken into consideration 
does not appear to be consistent with the decision of the Italian legislator to take 
into account years of service accrued by teaching staff on fixed-term contracts at 
State schools, who, in order to teach as substitute teachers, need simply request 
that they be included in the ranking lists, for which they need not pass the public 
selection process or possess any particular qualification as a teacher. 
Furthermore, teaching staff at educandati (girls’ schools run by religious bodies), 
scuole parificate (State-accredited primary schools), scuole sussidiarie e 
sussidiate (small State-funded schools run by private individuals or entities) and 
scuole popolari (schools for adult education) are also recruited without having to 
pass any type of selection process. 
14 Nor can the mere intention to avoid increased public spending justify 
discrimination as compared with permanent employees of the State.

15 The referring court therefore takes the view that the question of the interpretation 
of EU law must be referred for a preliminary ruling, pursuant to Article 267 
TFEU, in order to establish whether or not EU law precludes national legislation 
such as that contained in Article 485 of Legislative Decree No 297/94, which 
discriminates against teaching staff at scuole paritarie (State-equivalent schools) 
on fixed-term contracts as compared with permanent teaching staff at State 
schools, when assessing what rights they have accrued, despite the fact that 
superior professional skills resulting from length of service are completely 
unrelated to how the employee was recruited or, moreover, with the legal status, 
whether public or private, of the previous employer, as also demonstrated by the 
fact that the same legislator takes into account any teaching services provided at 
educandati (girls’ schools run by religious bodies) and private scuole parificate 
(State-accredited primary schools), scuole pareggiate (State-equivalent secondary 
schools), scuole sussidiate e sussidiarie (small State-funded schools run by private 
individuals or entities) and scuole popolari (schools for adult education) before 
the award of a permanent contract. 
16 This dispute, concerning the salary conditions applied to teaching staff who have 
been on fixed-term contracts when they are subsequently recruited as State 
employees, undoubtedly falls within the scope of ‘implementation of Union law’ 
within the meaning of Article 51(1) of the Charter. 
The question as to whether or not Article 485 of Legislative Decree No 297/94 is 
consistent with the general principles of equal treatment, equality and non-
discrimination in the area of employment conditions, now laid down in Articles 20 
and 21 of the Charter, must therefore also be examined, because the legislative 
decree precludes the taking into account, including only in part, of years of service 
solely in the case of workers on fixed-term contracts at scuole paritarie (State-
equivalent schools). 
17 The teaching experience gained with other employers before becoming a civil 
servant is identical for workers at scuole paritarie (State-equivalent schools), if 
not in fact superior to that earned in other private schools, in so far as only ‘(g) 
teaching staff [holding] a certificate of qualification as a teacher; [with] (h) 
individual employment contracts for managerial and teaching staff [that] comply 
with the national collective agreements in the sector’ can work there. Article 485 
of Legislative Decree No 297/94, on the other hand, attaches importance only to 
services provided at schools of a ‘lesser’ rank than that of scuole paritarie (State-
equivalent schools), seeing that, of all the schools it refers to, only scuole paritarie 
(State-equivalent schools) require their teaching staff to be in possession of a 
qualification as a teacher. 
18 In these circumstances, the referring court takes the view that it is necessary for 
the Court of Justice to make a ruling on interpretation. It can in fact uphold the 
applicant’s requests only if the interpretation of EU law precludes the national law 
at issue.
