The recent British decision of Jones v. Kaney points in that direction, and one expert in Canada says, “Bring it on” (via Erik Magraken):
I like Britain’s approach because everyone, including expert witnesses, should be responsible for their actions. … I make an error or I provide care that’s below standard, I should be held responsible and I am. I don’t see why that responsibility should disappear because I’m now acting as an expert on the witness stand in court.
