Haw. Rev. Stat. § 50
That upon the receipt of a veto message from the governor each house of the legislature shall enter the same at large upon its journal and proceed to reconsider such bill, or part of a bill, and again vote upon it by ayes and noes, which shall be entered upon its journal.
If after such reconsideration such bill, or part of a bill, shall be approved by a two-thirds vote of all the members to which each house is entitled, it shall thereby become law.
An act authorizing an issuance of bonds was held to take effect upon its passage over governor's veto, although by its terms it was to "take effect" upon "its approval by the president," the latter words being held intended to refer to president's approval of issuance of the bonds, under §55, and not to be an attempt to delegate power: 19 Hawai'i. 12; 26 Ops. 463.
