As the other provinces would have refused to sign the treaty if they had known of the secret clause, De Witt arranged that this clause would bind only the States of Holland. The
States-General of the Netherlands were completely left in the dark, as was the Frisian plenipotentiary at the negotiations,
Allart Pieter van Jongestall. Only the two Holland representatives (
Hieronymus van Beverningh and
Willem Nieupoort) were in on the secret. Consequently, the States-General ratified the treaty on April 22, 1654, without the secret annex. The prime movers behind the Act of Seclusion, in which
William III, Prince of Orange was excluded from the office of Stadtholder, were De Witt and his uncle
Cornelis de Graeff. Then, the States of Holland debated the Act and passed it on May 4, 1654, over the opposition of the Holland
ridderschap (delegates of the nobility, who had one vote in the States) and six of the cities (with one vote each). Only then did
Oliver Cromwell, the English signatory to the treaty, ratify the treaty (including the secret clause), as had been agreed beforehand. De Witt, managed to have the act ratified only with the greatest effort. The
Gedeputeerde Staten (Delegated States) of Friesland (executive of the
States of Friesland) even demanded that the conduct of the Dutch plenipotentiaries be investigated. ==Aftermath==
