Applicable Law

Under the 1935 Constitution and the doctrine of separation of powers, the Senate possesses implied coercive authority—including the power to punish contempt in aid of legislative functions—so long as due process is observed and discretion is not exercised arbitrarily.

Procedural History

Arnault’s 1950 refusal to disclose the recipient of ₱440,000 led the Senate to imprison him for contempt. He sought certiorari (G.R. No. L-3820), which this Court denied, upholding the Senate’s coercive power. After Arnault’s 1951 affidavit naming “Jess D.

Purging Contempt and Credibility

To purge contempt, a witness must provide a truthful, substantive answer. The Senate reasonably disbelieved Arnault’s naming of “Jess D. Santos” as the real recipient of the funds; instead, it deemed the claim a continu
