Questão jurídica principal
Whether the inheritance-partition appeal was admissible despite not joining all co-heirs as respondents.
Decisão extraída
No. A partition claim and related appeal must be directed against all co-heirs because the judgment has effect vis-à-vis all heirs and concerns jointly owned estate assets.
Fundamentação extraída
The appellant attacked only one co-heir at federal level, although the partition judgment necessarily affects the entire co-heir community. The non-joined co-heir could not be added ex officio or by joinder, and no clear and unequivocal declaration of procedural submission existed.
