Legal Question in Civil Rights Law in California

No one, powerful or not, can prevent you from filing properly prepared and served pleadings appropriate to the case, during clerk's office filing hours or online in many courts. Saying you are being prevented sounds 'delusional' unless you can show they waylaid you on the way to the courthouse with a gun. If so, report the crime to the police.

You've got a long way to go to prove improver behavior by court personnel. Saying it doesn't make it true, and it is highly unlikely to be true.

IF you have actual facts, and not just frustration that you aren't able to properly handle a case pro per, you can write to the Chief Clerk of the Court and explain your 'facts'. Opinions do NOT count. Don't even write or make such allegations anywhere without credible facts supported by admissible evidence.

I suggest you consult with local counsel for help with your case, if it has sufficient value to make those fees a reasonable action.
