In 2005, in its second periodic report to the Committee on the Rights of the Child, Oman stated:
We affirm that this principle is in effect, it being one of the fundaments of the penal legislation in the Sultanate, as stipulated in article 21 of the Basic Law of the State, which prescribes that there shall be no punishment except for acts subsequent to the entry into force of the law providing for those acts.
