Party's motion to execute before Labor Arbiter a waiver of right to relitigate

We must refuse, however, the petitioners plea for actual, moral, and exemplary damages. It must be emphasized that he did not appeal from the Labor Arbiters decision denying such claims for want of legal and factual basis; on the contrary, he moved for the immediate execution of that decision. The decision then became final as to him and by asking for its execution he was estopped from relitigating his claims for damages. [G.R. No. 117945. November 13, 1996]
