A Kingdom Act (Dutch: Rijkswet) is an act of the Kingdom of the Netherlands, which scope goes beyond the constituent country the Netherlands, and which is (also) effective in the other constituent countries Aruba, Curaçao and/or Sint Maarten.
An example of a Consensus Kingdom Act is the Kingdom Act on Financial Supervision of the Constituent Countries Curaçao and Sint Maarten, which was adopted as part of the package of legislation pertaining to the dissolution of the Netherlands Antilles.
Kingdom Acts are generally proposed by the Government of the Netherlands, after discussion in the Council of Ministers of the Kingdom (which consists of the Council of Ministers of the Netherlands together with the ministers-plenipotentiary of Aruba, Curaçao and Sint Maarten respectively).
When Aruba, Curaçao or Sint Maarten does not agree with the proposed Kingdom Act, then the country can increase the majority needed for approval in the States-General to 5/9 of the votes.
After approval in both houses of the States-General, the Act receives royal assent.
