The process goes like this:
1. Send a letter to the Commission explaining why you believe the law may have been violated,
2. Describe the specific facts and circumstances
3. Name the individuals or organizations responsible
4. Your complaint should also indicate which allegations are based on personal knowledge rather than on outside sources (for example, newspaper articles).
5. The letter must be sworn to, signed and notarized.
