Have not been able to read all the above posts, just one qs?
Has anyone botherd to mention what the chazon ish writes? u need a sanhedrin blishkas hagazis to throw someone out. Has anyone seen the sanhedrin or even a yeshivas beis din??
Personal story: i was in a yeshivah and someone made trble, i was called in and told “u did it” i said i dint, the menahell replied “ur a liar” long story short i was not kicked out but went a month without sleep, a while later i recieved a letter from a boy who already left the yeshivah asking for mechilah he lied and told the menahel i did it to save his friend… i begged the menahell then to believe me to no avail, i said do u have witnesses?? this menahell is no longer living, but he met me by a wedding yrs later and i totally ignored him.
