Can the alleged scientists at East Anglia be sued? Calling on the lawyers at this site.

Would appreciate the views of the lawyers on this site on this question.  Seems to me that the following might be possibilities:

1) They took public monies from God knows how many governments, then committed fraud.

2) The libel laws in Great Britain are much more tilted towards the plaintiff than ours are.  If the “researchers” said bad things about a skeptic in public, well…

3) Their political activism disguised as science created real economic damages to countless companies and citizens.

I could probably continue with a speculative list.  Any informed ideas on the subject?  (Calling Brad Smith!)
