The makers of a Channel 4 documentary have confirmed they are suing West Midlands Police and the Crown Prosecution Service (CPS) for libel.
The Dispatches programme, Undercover Mosque, tackled claims of Islamic extremism in the West Midlands.
In November media regulator Ofcom rejected police and CPS claims the programme was heavily edited and distorted preachers' comments.
The force said itself and the CPS were in talks with the programme's makers.
A statement on behalf of Dispatches editor Kevin Sutcliffe and programme makers Hardcash Productions said: "The statements made by both the West Midlands Police and the CPS were completely unfounded and seriously damaging to our reputation.
