Invoking Constructive Res Judicata in a case can have significant legal consequences, primarily by barring the re-litigation of issues that could have been raised in a previous suit. The main consequence is that it prevents parties from revisiting matters that were either directly or constructively addressed in earlier proceedings, even if those issues were not formally litigated. This results in the finality of judgments, ensuring that once a matter has been decided, it cannot be endlessly contested. For the parties involved, this doctrine can limit their ability to pursue certain claims or defenses, potentially infringing on their right to a fair hearing if they were unable to raise the issue previously due to valid reasons. However, it also serves to protect the opposing party from continuous litigation on the same matters, promoting judicial efficiency. In essence, it can safeguard both the rights of parties by preventing the unfair reopening of resolved matters, while simultaneously protecting the court's resources from repetitive cases.
