Final answer:
In the complaint filing process, a complainant files a complaint form, the relevant agency opens a file for the investigation, and the complainant is informed when the investigation starts.
Step-by-step explanation:
Three parts of the complaint filing process are: 1) The complainant files a Statement of Complaint form; 3) LARA (or a similar agency) opens a correspondence file for the investigation; and 4) The complainant is notified within 15 days that an investigation has begun.
The attorney general subpoenaing the complaint filing process is not typically a direct part of the initial steps of filing a complaint. The investigation process includes the collection of facts and examinations that follow the filing of a complaint. Moreover, during the judicial process, the solicitor general may become involved, especially in Supreme Court cases, by preparing petitions and briefs, as well as presenting oral arguments. It is important to note that the right to a speedy and public trial, among other rights, is preserved for the accused throughout the criminal prosecution process.
