As soon as some students came to know about rejection of nomination papers filed by Sher Hang Subba, Aniras Luitel and Nishant Subedi -- all final year students -- many of them boycotted classes and reached near the college gate where they staged a dharna demanding restoration of nomination of these candidates.
The Students Representative Council election is scheduled for November 9.
The college's dean Ajay Chhetri, however, defended the election panel's decision saying that there were disciplinary charges against these students.
He, however, said the three students will be given an opportunity tomorrow to defend themselves before the election authorities.
During the disquiet in college premises, its principal Lily Alley was absent as she was hospitalised due to some health problems, according to Chhetri.
Sikkim Government College has 3,500 students.
