Enrolled bill doctrine
The enrolled bill rule is a principle of judicial interpretation of rules of procedure in legislative bodies. Under the doctrine, once a bill passes a legislative body and is signed into law, the courts assume that all rules of procedure in the enactment process were properly followed. (https://en.wikipedia.org/wiki/Enrolled_bill_rule)Under the "enrolled bill doctrine," the signing of a bill by the Speaker of the House and the Senate President and the certification of the Secretaries of both Houses of Congress that it was passed are conclusive of its due enactment. A review of cases reveals the Court’s consistent adherence to the rule. The Court finds no reason to deviate from the salutary rule in this case where the irregularities alleged by the petitioners mostly involved the internal rules of Congress, e.g., creation of the 2nd or 3rd Bicameral Conference Committee by the House. This Court is not the proper forum for the enforcement of these internal rules of Congress, whether House or Senate. Parliamentary rules are merely procedural and with their observance the courts have no concern. Whatever doubts there may be as to the formal validity of Rep. Act No. 9006 must be resolved in its favor.The Court reiterates its ruling in Arroyo vs. De Venecia, viz.:
But the cases, both here and abroad, in varying forms of expression, all deny to the courts the power to inquire into allegations that, in enacting a law, a House of Congress failed to comply with its own rules, in the absence of showing that there was a violation of a constitutional provision or the rights of private individuals. In OsmeƱa v. Pendatun, it was held: "At any rate, courts have declared that ‘the rules adopted by deliberative bodies are subject to revocation, modification or waiver at the pleasure of the body adopting them.’ And it has been said that "Parliamentary rules are merely procedural, and with their observance, the courts have no concern. They may be waived or disregarded by the legislative body." Consequently, "mere failure to conform to parliamentary usage will not invalidate the action (taken by a deliberative body) when the requisite number of members have agreed to a particular measure." (G.R. No. 168056; September 1, 2005)
