Get lawyers out of the process when they don't need to be there. Allow the two sides to plainly state their case before a judge or arbitrator and decide the matter swiftly. Get people accustomed to working out their differences amicably again. Force loosing party to pay all court costs. Establish strict rules on what constitutes a reasonable suit.
Current rules make it tough for justice to prevail.
Consider amendment to repeal part of 5th amendment relating to right to refuse to testify on grounds of incriminating oneself. The bottom line is that justice must be based on truth. Society should permit whatever means is most expeditious to getting to that truth. Or any other means that is reasonably reliable. At the very least these should be elective on the part of the accused and might result in a quick acquittal, saving time and possibly preventing innocent people from being incarcerated awaiting trial, or worst yet convicted on circumstantial evidence as the guy from Canada who spent 10 years in prison until analysis of DNA evidence proved that he was not guilty.
