Federal law apparently has nothing to do with this situation.

State Supreme Courts interpret their state's constitution and it applies to that state only. If it implicates the US Constitution it might be challenged in federal court but that is a long shot.

If another state has the same statute and has ruled on that statute and your state has not, then you could cite those cases as guidance for the court. You could make use of the legal arguments provided they are not too fact specific. The case is guidance but it is not controlling, meaning that no court in another state has to follow it.

Also, keep in mind that state appeals courts can also come to different decisions, and the conflict will usually be resolved by their supreme court.

You will also find that appeals courts and especially state supreme courts will usually decide only the points of law they have to decide. Most decisions are narrowly tailored and you really need a good legal mind to understand exactly what they say and their application. It is rare that a high court rules on the actual constitutionality of a statute.

You obviously are not an attorney and it sounds like you are in over your head.
