Two intervening petitions have been filed with Sri Lanka's Supreme Court backing the Government's proposed 22nd Amendment to the Constitution, arguing it can be enacted without a referendum.

Two additional petitions have been submitted to the Supreme Court expressing support for the Government's 22nd Amendment to the Constitution Bill, which is currently before Parliament. The petitions were filed by Sarath Manamendra, leader of the New Sinhala Heritage organization, and K. Sarath Lal Perera, General Secretary of the National Organization for the Protection of Retired Rights.

Both petitions make similar legal arguments regarding the Bill's procedural validity. The submissions contend that the legislation has been presented to Parliament in accordance with constitutional requirements and request that the Supreme Court rule the measure can be enacted without necessitating a public referendum.

The filing of these supporting petitions indicates ongoing legal proceedings surrounding the proposed amendment. The Supreme Court will need to consider these submissions alongside any opposing arguments as it determines the constitutional propriety of the Bill's passage. The outcome of these proceedings will likely prove significant for the amendment's path forward in Parliament.
