 excerpt: It is something everyone talks about and takes a passing interest in. But when it comes to casting votes, most of the junta can be found feigning sweet slumber on that fateful Sunday morning. And hence, politics at IIT Roorkee inevitably boils down to a select set of kingmakers and their minions.

 What is the SAC? How does it function, and who are its representatives? Beyond a few fuzzy beliefs, an unnervingly large section of the student population has little, if any answer to these questions.

 excerpt: The pre-existing power has been broken down to pieces and redistributed. But further empowerment has been ominously disregarded. Even more disturbingly, there has been no discussion of handing more power to the students. The system is still wholly patronizing, regarding a campus full of adults like petulant children unable to think for themselves.

 categories: [wona, column, cover]
 tag: news
 excerpt: From dictatorial campaign rules to curbed leeway, there were enough reasons for the candidates to be vexed right from the start. Even the most apathetic voter has been victim, with the administration imposing restraints on inter-bhawan movements and gatherings on campus. As the whole campus brims with door to door campaigns and last minute calculations, WatchOut!, revamps the WatchOut! Redressal Cell (WORC) and sets out to examine how the IITR junta respond to the mighty election campaigns and the resulting restrictions to life on campus.
