A contentious decision by one of Victoria Police's most senior officers to not proceed with charges of perverting the course of justice or perjury against two policemen will be reviewed by the Office of Public Prosecutions.

Assistant Commissioner Brett Guerin ignored the recommendations of an internal police investigation when he decided not to lay the charges against the two officers, who allegedly assaulted two teenagers in 2014.

Mr Guerin, who is responsible for internal force watchdog the Professional Standards Command, also chose not to consult the OPP before he proceeded with assault charges against Leading Senior Constables Dennis Gundrill and Simon Mareangareu over an alleged altercation outside a Vermont convenience store.

According to correspondence obtained by Fairfax Media, the serious allegations of perjury and attempting to pervert the course of justice will be dealt with by an internal disciplinary hearing.
