I doubt this trend. It is nearly impossible to win a legal malpractice case. Say the odds of wining a single negligence trial is 50%. One must win two trials, show the usual elements of professional malpractice. Then prove that the original case would have been won, so the odds are 25%. If that takes place, the defendant will still claim the attorney judgment rule.
Now prove the ability to collect after winning both trials. Say, 50% again. So, the odds are 1 in 8 of winning, assuming strong evidence. The judge is a lawyer and is totally biased in favor of his campaign donors, mostly attorneys. So the 1 in 8 chance represents a marked overestimate of the chance of success, since sabotage of the plaintiff is ongoing the entire trial.
