The Duke was a Protestant when the decision was given. Nor was it promptly given. The application was made to the Southwark diocesan court in 1925. This court, after scrutinizing all the evidence, gave judgment in February, 1926, that the first marriage was invalid from the beginning. Rome, not opposing the decision, but lest it might have been given too easily, called the case to the Holy See. The whole matter was reviewed, sworn testimony being obtained in America and England. The Holy See arrived at the same decision as Southwark and decreed nullity accordingly, six months later. You can hardly call that promptly.
