The seven teachers - Atul Gupta, Ish Mishra, P K Vijayan, Poonam Sethi, Ratan Lal, Rajesh Kumar and Sachin Vashistha - had last year written to L-G Najeeb Jung, alleging irregularities in construction of a girls' hostel, following which an inquiry committee was set up which found them guilty of "gross misconduct" and "defaming the college".
The written order served on seven teachers by the Principal lists the punitive actions to be taken against them including loss of two annual increments and being debarred from holding any administrative post for five years.
The decision was taken in the GB meeting held on last Friday.
DUTA condemned the move as a "draconian" action by the college authorities and demanded revoking the order.
"The order will prevent the seven teachers from working as members of Staff Council committees, where they could articulate concerns about the functioning of the college, including the hostel and admissions.
