Para. 30: “Indeed, the principle of equality of salary, which implies the elimination of salary discrimination based on whatever criteria that may relate to the person of the salaried worker, does not apply to the diversity of the sources of remuneration. Here, the salaries proposed by the Defendants are to be paid, not from the funds of the Commonwealth, but from the budget of the Defendants themselves. This was what was established as a principle, by Court of Justice of the European Union, in the 17th September 2002 Judgment on Lawrence and Regent Office Care Ltd. & Others (Report 1-07325-C.C.E.E.) when it stated that “the principle of equal work, equal salary, does not apply when the observed disparities in remuneration cannot be attributed to a single source’.”
