The leader of the Pivithuru Hela Urumaya (PHU), Udaya Gammanpila has filed a petition with Sri Lanka's Supreme court to challenge the draft bill of the 20th Amendment to the Constitution, presented previously by the Janatha Vimukthi Peramuna (JVP).
Gammanpila claims the proposed Amendment, tabled in parliament this week, is a violation of the Constitution of Sri Lanka.
Sri Lanka's Speaker informed parliament last year that the proposed 20th Amendment would need a two third majority in parliament before being put before the public via a referendum in order to be implemented following a Supreme Court ruling.
