Insurance law firm Reynolds Porter Chamberlain (RPC) is warning that professional indemnity insurers may be forced to increase their reserving levels after recent decisions in the Court of Appeal and the High Court.

Up until two years ago, all claims were automatically barred for 15 years after the relevant events happened. This ruling applied unless key information had been deliberately concealed.

But RPC says a Court of Appeal case in 1999,

Armitage & Guest, removed the time limit on all acts "deliberately done" that caused a breach of a professional's duty of care.
