Key legal question
Whether a single heir may request inspection of the deceased taxpayer’s tax files without the consent of all co-heirs.
Extracted holding
Yes. The right to information and inspection belongs to each heir individually; mutual consent of the co-heirs is not required.
Extracted reasoning
By universal succession, heirs step into the deceased’s tax procedural position. Each heir may independently safeguard his interests and therefore request access to the tax files.
