My question involves civil rights in the State of California, but is primarily a question about federal protections under the constitution:
The county I live in is accusing me of zoning violations. I have read the codes in their complaint, and do not believe I am in violation: Their procedure does not allow me to defend myself and present evidence to support my innocence, and in fact, to get this resolved, I must sign an affidavit admitting to these violations, then go before a hearing officer to determine my punishment and see if I will be able to clear the violations.
I think that by not allowing me to present evidence in support of my innocence, my right to due process is being violated. Also, by forcing me to sign an affidavit acknowledging my guilt, I believe the 5th amendment prohibiting forced self incrimination is also violated.
Am I right, and if so, what do I do?
