Criticism to Res Judicata

Res judicata can also be applied to judgment that may be contrary to law. The doctrine of res judicata has been used for a long time and it encloses the general effect of one judgement upon another trial or proceeding. It includes matters not only those of bar but also those matters which should be litigated. For example, if a case has been dismissed on a specific ground by a court of law or equity and it is not deemed as a final judgment and technically res judicata will apply but it is not justified. If the chancellor has denied equitable relief on a principle but it was held by the court that the plaintiff is barred from proceeding as a legal remedy. Most of the equity cases involve res judicata and do not get beyond collateral estoppel. As it raises the difficulty of overlapping more than the failure to litigate issues. 

The title to real estate and the right to collect rent depended upon one and the same construction of a will. In an interpleader over the rents, A got the decree. B appealed, without supersedeas, and secured a reversal, but, before his appeal was decided, A had sued him in ejectment, invoking the decree, and recovered a judgment for the real estate. B did not appeal from this judgment, but, after the reversal of the decree, he sued A in ejectment for the land, relying upon the reversal.
