Whether U.________'s objection to his appointment as curator still had a legal purpose after P.________'s death.
The objection had become moot because the ward died; the appellant no longer had a legal interest in the proceedings.
A legal interest is required for admissibility even in non-contentious proceedings. Since P.________ died after the objection was filed, the challenge lost its object and interest, so the court merely took note and struck the case from the docket.
