This discussion clarifies whether constructive res judicata, as outlined in Section 11 Explanation IV of the Code of Civil Procedure, applies even if a plaintiff was not cross-examined or did not appear as a witness. The consensus is that it generally will apply if the core issues in both suits are the same and were decided in the first instance. While the absence of cross-examination might affect the weight of evidence, it doesn't automatically prevent res judicata from barring a subsequent suit on the same matter.
