Welsh: Deddf Hawliau Prydeinig
English: British Bill of Rights
Status B
Subject: Law
Part of speech: Noun, Feminine, Singular
Definition: Deddfwriaeth arfaethedig gan Lywodraeth y DU a fyddai’n disodli Deddf Hawliau Dynol 1998.
Notes: Nid yn yr ystyr “deddf ddrafft” y defnyddir y gair “Bill” yn y term hwn, ond yn hytrach “written document or statement”. Deddfwriaeth sy’n datgan hawliau a dyletswyddau cyfreithiol a sifil dinasyddion a’r wladwriaeth yw “Bill of Rights”. Dehonglir bod yr ansoddair “Prydeinig” yn y term hwn yn disgrifio’r hawliau yn hytrach na’r ddeddf, ac felly nid yw wedi ei dreiglo.
