That Res judicata prevents successive suits involving the same factual setting between
the same parties and brings disputes to a conclusion. A matter once litigated and legally
determined is conclusive between the parties in all subsequent proceedings.
Case for Discussion:
1. Cummings v. Dresher, 218 N.E.2d 688 (N.Y. 1966).
There was a collision between an automobile owned by Mr. Cummings but driven by
Mrs. Cummings and one driven by Bernard Dresher. Henry Dresher, the brother of the
driver, was a passenger in the Dresher car. Both Bernard and Henry sued Mr. and Mrs.
Cummings in the federal court for damages for their injuries. The jury in that case found
Mrs. Cummings was negligent and also found Bernard Dresher was negligent. Based
upon the doctrine of contributory negligence, Bernard was not allowed to collect
damages. However, Henry was awarded damages since he was not the negligent driver.
Subsequently Mr. Cummings filed suit against Bernard Dresher for damages to the car
sustained in the collision. This suit was brought in a state court, and Bernard Dresher
sought a summary judgment on the ground of res judicata.
Issue: Is a federal court decision res judicata for a later state court action involving the
same parties and the same events?
Held: Yes. When a full opportunity has been provided to a party in a prior action to
prove his or her freedom from liability or to establish liability on the part of another,
there is no reason for permitting him or her to retry those issues. In the first case, both
drivers were found to be at fault. One who has had his or her day in court cannot
relitigate the issues. The judgment in the first trial is conclusive.
