The Nitirat group has voiced opposition to a general amnesty for all political offenders proposed as part of the government's attempts to achieve national reconciliation.
Nitirat core leader and law lecturer at Thammasat University Worajet Pakeerat said the group disagreed with the proposed blanket amnesty which would exonerate all political offenders as well as state authorities responsible for cracking down on protesters.
While an amnesty should be granted to ordinary people who took part in various protests after the military coup that toppled the Thaksin Shinawatra government on Sept 19, 2006, state authorities who were responsible for dispersing the protesters should not be let off the hook, Mr Worajet said.
He said the constitution should be amended to include a provision regarding conflict resolution.
Under the provision, a committee would be set up to resolve conflicts, with a set of remedial measures in place.
The proposed amendment to establish the new provision could proceed immediately and independently of the government's ongoing charter rewrite move, Mr Worajet said.
He also proposed that the new constitution, which is being pushed by the government, contain a clause which nullifies all the judicial decisions which were a consequence of the 2006 coup.
These include the decisions and the work of the the now-defunct Assets Scrutiny Committee set up by the coup makers to investigate alleged corruption by Thaksin.
Mr Worajet said the proposal was not intended as an amnesty but was meant to start the judicial process anew to ensure justice.
He said the Nitirat group, which comprises the university's law lecturers, will continue campaigning for an amendment to Section 112 of the Criminal Code, or the lese majeste law.
At least 10,000 signatures have now been gathered and will be presented to parliament to push for the amendment, Mr Worajet said.
