Art. 2086.Right of Third Person to Appeal

Intervention lets a nonparty with a stake in pending litigation join the case before judgment. Article 2086 gives that same category of person an appellate remedy when intervention never happened: anyone who could have intervened at the trial court level may appeal the judgment that came out of it, effectively opening a path into the case at the appellate stage for someone who was eligible to join it earlier but did not.

The right does not depend on what other parties have done. Article 2086 specifically allows this third-person appeal "whether or not any other appeal has been taken," so a person eligible to have intervened can appeal on their own even where no party to the suit appealed at all, or can pursue an appeal alongside one a party already filed.

The rule protects people whose interests are affected by a judgment even though they never formally joined the lawsuit, giving them a way to contest an adverse outcome despite having stayed out of the trial court proceedings. A third person appealing under this article is still bound by the same delays for taking an appeal that run from the judgment, whether the appeal taken is devolutive or suspensive.
