I was wondering if anyone knew anything regarding does a sorority have a right to come into your room and search your belongings without probable cause. I currently live in my sorority house and there has been a few people drinking that lived in but nothing too serious/no one caught in trouble for it but then out of the blue they said it can't happen anymore and the chapter adviser went into every room, despite there being evidence of any drugs existing, and went through everyone's stuff. is that illegal? any thoughts.
