What must a verified written complaint include for investigation?

A verified written complaint must include evidence supporting the claims of violation because it provides a basis for the allegations being made. This evidence is essential for any investigative body to accurately assess the validity of the claims and determine whether further action is needed. Including evidence strengthens the complaint by giving investigators concrete information that can be verified and fosters an efficient resolution process.

In this context, the other options do not meet the necessary criteria for a complaint. A claim of past violations might be relevant, but it does not address the requirement for substantiation through evidence. Indicating potential future violations does not suffice as a basis for an investigation without past or present proof of wrongdoing. Additionally, providing a summary of a person's character is not pertinent to the investigation of specific claims or violations and does not contribute to the necessary factual basis for the complaint. In summary, without evidence, a complaint lacks the necessary foundation to warrant serious consideration or investigation.
