Key legal question
Whether the Federal Supreme Court could review the estate administration order only as a provisional measure.
Extracted holding
The challenged order was a provisional measure because it served only to secure and manage the estate temporarily without deciding substantive succession rights.
Extracted reasoning
Official administration under Art. 490(3) CC, read with Art. 554 CC, protects the estate's preservation and does not prejudge ownership or inheritance claims; therefore review is limited by Art. 98 LTF to constitutional complaints.
