Questão jurídica principal
Whether the complaint had to be discontinued after the appellant's death and the heirs' failure to validly enter the proceedings.
Decisão extraída
The complaint became moot and was struck from the docket because no valid procedural succession occurred.
Fundamentação extraída
The heirs did not file the required inheritance certificate or valid declarations of entry within the extended deadline; only all heirs or their common representative may act on behalf of an estate, and no exception applied.
