"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, directly or indirectly, in respect of his employment from his employer."
"In such situations, at least, Article 119 is directly applicable and may thus give rise to individual rights which the courts must protect."
"... priority over anything in our English statute on equal pay which is inconsistent with Article 119."That priority is given by our own law. It is given by theEuropean Communities Act 1972 itself ... . The woman is entitled to equal pay for equal work, even when the woman is employed after the man has left. That interpretation must be given by all the courts of England. It will apply in this case and in any such case hereafter."
