Key legal question
Whether a civil judge is competent to hear a mistake-based challenge to an express acceptance of an inheritance
Extracted holding
Yes. Such a dispute concerns a contested private-law claim and must be decided by the civil judge, not an administrative authority.
Extracted reasoning
The court held that declarations of acceptance are not absolutely irrevocable and may be challenged for will defects. The relevant dispute is judicial in nature; the first instance therefore had subject-matter jurisdiction.
