In case involving plaintiff's removal from position as a police officer, rejection of argument that defendant-city violated plaintiff's right to have the investigation into his conduct completed within the one-year statute of limitations found in the Public Safety Officers Procedural Bill of Rights Act is affirmed where plaintiff's failure to raise the statute of limitations before the Board of Rights, and his failure to seek injunctive relief for the alleged violation under Government Code section 3309.5, preclude appellate review of the issue.
