LAST EDITED ON Jul-18-11 AT 03:33PM (MST)[p]FYI- WY has two different trespass laws. The G&F law and the criminal trespass.
The criminal trespass law can not be enforced by wardens, so the Sheriff's Office would be called to take the report. In WY it is every citizen's right to be the complainant on a crime not committed in the presence (or even in the presence) of a law enforcement officer (LEO). The LEO should establish that there is probable cause (PC) that a crime as been committed, and that you committed the crime. If PC is established a citation can be issued, unless you meet certain criteria. If you meet that criteria you can be arrested, and would be required to post a bond. Some law enforcement agencies may direct the complainant to fill out a citizen's affidavit, and you may summoned to court if the county attorney believes there was a crime committed.
It would be best to call and speak with the county attorney and get his views on both laws as they pertain to corner crossing. I would write down the person you spoke to, time, and date. Sometimes, Assistant District Attorneys have different views on the law, but it ultimately left up to the elected county attorney if charges should proceed. It would be difficult for an county attorney to press charges if his people advised it was not illegal. It would be embarrassing for the county attorney when his assistant was subpoenaed to testify by you.
IMO, the crime would be very difficult to proof beyond a reasonable doubt. Keep in mind, it takes money to hire a private attorney, so it is best to make a phone call to the county attorney. It would be expensive to hire an attorney, but for you NR, you would have the expense of traveling back to WY for the court date. You could certainly win the case, pro se, with some common sense questions. It would be cheaper too!
You have to intent to break the law, and I don't see where someone corner crossing has the intent to trespass upon private land. That's just my opinion.
