You must give the court a reason why someone from the public is barred from a public place
Depends on local laws but in the US everyone is invited to attend a public meeting in a KH. The invitation to attend a KH is a license that can be revoked. A KH is a private place not public. When a person's invitation is revoked such person has no right to be there and can be arrested for trespassing. If such person claims that he was being treated in violation of the law, the burden of proof is on the person making the accusation, but that is another matter all together.
