Thammasat University on Thursday denied permission for an anti-government rally at its Tha Phra Chan campus scheduled for Sept 19.
The university said that the organiser had yet to comply with its guidelines on holding political activities on campus.
The rejection came a day after Parit Chiwarak, a core member of the students' Free Youth group, unveiled details of the "Sept 19: Return power to civilians" rally while a group of alumni stepped up calls for the university administrators to ban the event.
The university's guidelines, which were issued on Sept 3, were designed to promote learning about civil rights, liberties and responsibility while obeying the law and the constitution and taking into account the safety of the students, according to a statement by the university.
However, Mr Parit, also known as Penguin, was defiant after the university issued the statement. He posted a Facebook message saying that the rally would go ahead anyway.
"Although executives of Thammasat University will not allow the venue at Tha Prachan to be used for the gathering, we will still hold it at Thammasat because Thammasat belongs to the people, not to some dictators' lackeys," he wrote.
