FOI requests should be reserved for much more interesting things like how much does it cost an FRS to lose a determination.
Not unless you're a historian or a narcissist showcasing former glories.
Seriously though, I personally salute those who seek determinations (including you Colin, but only when you're not being smug about it), FRSs that are brave enough to agree to them and the Secratary of State for being impartial enough to, where necessary, rule against a FRS.
Whichever way a determination eventually goes it gives our industry a national perspective of what is considered reasonable in the circumstances, win or lose it's public money well spent.
Unfortunately, other than the Courts, there doesn't appear to be any impartial determination mechanism for challenging LFB/WYFR&S policies on charging for attendance at false alarms (which differ significantly).
