The protest call prompted college authorities to put up a notice signed by Principal John Varghese on Thursday, saying there should be no "disturbance of working environment" in the college and those doing that will be dealt within the Central Civil Services (Conduct) Rules.
The college has also banned the entry of media persons in the premises.
Teachers said the CCS rules apply to bureaucrats and not to them.
According to the Central Civil Services Conduct Rules, no government servant shall make any statement of fact or opinion which has the effect of an adverse criticism of any current or recent policy of the central government or a state government.
The notice put up by the college authorities also stated that there are examinations being conducted at present in the institution and any form of disruption to the exams will be dealt with strictly.
According to the college constitution, the Supreme Council of the college shall have the control of the religious and moral instruction of students of the college and of all matters affecting its religious character as a Christian college of the Church of North India.
Three members of the governing body -- Nandita Narain, N P Ashley and Abhishek Singh -- condemned the "illegal and unacademic decision taken by the Principal", that "could compromise the academic integrity of our admissions process" while demanding its withdrawal. They were also issued warning letters.
