 A few of the changes frequently advocated include limits on punitive damages, limits on non-economic damages, limiting the collateral source doctrine, use of court-appointed expert witnesses, elimination of elections for judges, reducing appeal bond requirements for defendants faced with bankruptcy, "venue reform", which limits the jurisdictions within which one can file a lawsuit, limits on contingency fees, the adoption of the English Rule of "loser pays" (the defeated party must pay both the plaintiff's and the defendant's expenses), and requiring that class action lawsuits with nationwide plaintiffs be tried in federal courts, eliminating awards for pre-judgment interest.Many of these measures tend to benefit defendants; others, such as the English rule, sanctions for delay, and early-offer settlement requirements, could have benefits to plaintiffs in some cases.Not all tort reform supporters support all proposed tort reforms.
