In arbitration, the parties to the dispute select an independent arbitrator who hears evidence from both parties and decides how the dispute should be resolved. In civil litigation, a judge or jury hears the evidence from both parties and decides how the dispute should be resolved. What are the differences between arbitration and civil litigation? Why is one approach better than the other approach to resolving disputes?
