Mandatory court date probably means exactly what it sounds like - you have to go to court. The "Stop Stand Park Prohibit" thing is probably a charge code that may cover the ordinance under which you are charged. Read through the tickets again and make sure they are for the same thing - you may be able to assert double jeopardy.
The answer to this question is not intended to be construed as legal advice. Nothing in this answer creates an attorney/client relationship. I do not represent you. If you wish to consult me regarding representation, please visit my website at www.blfattorney.com
This is the statute that I think your charge falls under. http://www.moga.mo.gov/statutes/c300-399/3000000440.htm Without knowing more facts I would say that you need to seek legal advice to go to court. If the ticket states that it is a mandatory appearance and you fail to appear, a warrant will be issued for your arrest.
If you have not found an attorney you can contact my office at 816-472-4357 and fax or email the tickets to my office. I would be happy to do a free review to let you know what can be done.
