Mewn dyfarniad dyddiedig 26 Gorffennaf, dyfarnodd y Goruchaf Lys o blaid yr Undeb Llafur, Unison, a gefnogwyd gan y Comisiwn Cydraddoldeb a Hawliau Dynol ac Undeb Gweithwyr Annibynnol Prydain Fawr. Wrth gynnal her Unison mewn perthynas â chyflwyno ffioedd ar gyfer Tribiwnlysoedd Cyflogaeth gan y Weinyddiaeth Gyfiawnder, llwyddodd y Goruchaf Lys i sicrhau diweddglo i achos hirfaith trwy'r llysoedd a ddechreuodd yn 2013 ac sy'n dangos rôl hanfodol undebau yn ein cymdeithas fodern, gan sicrhau nad yw gweithwyr cyflogedig cyffredin yn cael eu hecsbloetio gan arferion anghyfreithiol.
In a judgment dated 26 July, the Supreme Court found in favour of the trade union, Unison, who were supported by the Equality and Human Rights Commission and the Independent Workers Union of Great Britain. In upholding Unison’s challenge to the introduction of Employment Tribunal fees by the Ministry of Justice, the Supreme Court’s judgment brought a successful conclusion to long-running action through the courts which began in 2013 and which shows the vital role that unions play in our modern society, ensuring that ordinary workers are not exploited by illegal practices.
