The university collected 682 signatures on Sunday alone in reaffirming it stand against the bill.
Rector Somkit Lertpaithoon said the bill should only benefit people who took part in the political rallies and not those in government or who are involved in corruption cases.
He added the bill is unconstitutional because it appeared to pardon politicians who had committed illegal acts.
A total of 636 Thammasat lecturers and 46 of the university’s employees signed the petition. Somkit said university's alumni will gather at the statue of university founder Pridi Banomyong on this Thursday. They will file a petition with the president of the Senate.
