Non-practising lawyer M. Ravi, 48, has been barred from instituting legal proceedings against the government, the Attorney-General or the public prosecutor without the High Court's permission.

The Attorney-General's Chambers (AGC) applied to prevent what it said was abuse of the court process through his past legal actions under Section 74 of the Supreme Court of Judicature Act at the High Court on Wednesday .

In a statement yesterday, the AGC spokesman said: "Mr M. Ravi has, over the course of 11 years - since 2006 - habitually and persistently, and without any reasonable ground, instituted... vexatious legal proceedings against the Government, the Attorney-General and the public prosecutor."

The AGC highlighted six of Ravi's cases which it said were "vexatious legal proceedings".

In 2011, he made an application against the Government and Hindu Endowments Board (HEB) to challenge the constitutionality of HEB's Thaipusam procession guidelines. The High Court dismissed it.

This year, Ravi made an application against the Attorney-General to challenge the constitutionality of the elected presidency. The High Court also dismissed it and, in its written judgment, held that the application was "unmeritorious in almost every conceivable aspect" and an "abuse of process".

Separately, Ravi is facing criminal charges in the State Courts including one count each of assault and causing hurt by committing a rash act. He allegedly pushed lawyer Jeannette Chong-Aruldoss and threw a bag at lawyer Nakoorsha Abdul Kadir at The Adelphi building in Coleman Street on Aug 8.
