Labor law claim dismissed by court for not raising statute of limitations objection on its own motion.

The Supreme Court ruled that labor courts must not consider the statute of limitations ex officio but only upon the debtor's objection. The plaintiff argued that the lower court erred by dismissing the claim based on the expiration of the limitation period without a formal objection. The court rejected this, stating that the statutory language requires the debtor to actively invoke the defense, and the court lacks the authority to apply it sua sponte.
