Articles 42 and 43 of Federal Constitution are inseparable, like ‘irama dan lagu, tidak boleh dipisahkan’ — Hafiz Hassan

In Malaysia, Articles 42 and 43 of the Federal Constitution are considered inseparable, similar to "irma dan lagu, tidak boleh dipisahkan" — according to Hafiz Hassan. Royal prerogatives are legal powers that are exercised without needing parliamentary approval in the UK, where parliament holds supreme authority. However, most of these powers have been abolished, delegated to ministers, or replaced by statutes.

The prerogative, or simply the prerogative, is used by the monarch and their ministers and servants in running the government's functions. This power is significant in the UK, despite having no written constitution, as it is a challenging concept to define with various conflicting definitions. In Malaysia, the Supreme Court in the 1986 case of Superintendent Of Pudu Prison & Ors v Sim Kie Chon considered Article 42 as a reiteration of the RPM exercisable on the advice of the Pardons Board, which preserves the power of mercy in the country.
