98It is admittedly implicit in that judgment that the Community legislature is entitled to adopt, for the future, staff regulations which are less favourable for officials. However, in that judgment the Court stated that the validity of transitional measures safeguarding the rights lawfully acquired by officials recruited under former, more favourable, staff regulations could not be called into question, and concluded that those transitional measures did not discriminate against an official recruited under the new, less favourable, staff regulations. The Court took care in its review of the disputed measures to check that the difference of treatment between, on the one hand, an official recruited under the former, more favourable, staff regulations who continues, after the new, less favourable, regulations are adopted, to benefit from transitional arrangements safeguarding his rights and, on the other hand, an official recruited under the new, less favourable, staff regulations, was objectively justified. The Court held in that regard, first, that the official recruited under the new staff regulations could not rely on the former, more favourable, regulations and, secondly, that the transitional arrangements benefiting officials recruited under the former, more favourable, staff regulations could not be called into question.
