In 1544, Don Henry (who then occupied the see of Evora), and Cardinal Don Juan Pardo de Tabera, inquisitor-general of Spain, with the consent of their respective sovereigns, published a circular, in which they announced, that as the two states were so near each other, and the extent of the frontier favoured the flight of the persons prosecuted by the Inquisition, they had agreed, 1st, to communicate reciprocally everything which might interest the Inquisition; 2nd, to arrest in their respective jurisdictions those subjects who were designated; 3rdly, to keep them prisoners, and to claim the writings of the trial, because this measure was less inconvenient than the exchange of the prisoners. This convention was observed for some time; but in 1588 the inquisitors of Lisbon sent a requisition to those of Valladolid, to deliver up to them Gonzales Baez, who had been arrested at Medina del Campo: they replied that this demand could not be admitted, as it was contrary to the convention. The inquisitors of Portugal acknowledged the justice of this claim; but those of Spain, who in 1568 found themselves in the same situation, refused to conform to the measure, because they had at their head Cardinal Espinosa, who was all-powerful with Philip. The cardinal informed Don Henry that he had not ratified the convention, and that he considered it more proper that the prisoner should be given up to the tribunal which had instituted the trial. He requested Cardinal Henry to apply to both their sovereigns, and promised to propose to the King of Spain a measure which should be a general rule for all cases in future. Don Henry commissioned Francis Pereira, the Portuguese ambassador at Madrid, to terminate this dispute with Cardinal Espinosa. While this affair was being negotiated, several Spaniards who had been condemned by the tribunal of Llerena to be burnt in effigy as contumacious, were arrested in Portugal by the inquisitors of Evora, who immediately demanded the writings of the trial according to the convention of 1544. The tribunal of Llerena replied that it was impossible not to follow the example of Cardinal Espinosa. Almost at the same time these inquisitors arrested some Portuguese who had escaped from their country. The Bishop of Portalegre, inquisitor of Evora, reclaimed the prisoners, but the tribunal refused to give them up, if the inhabitants of Albuquerque, who had been arrested by the Inquisition of Evora, were not returned. Cardinal Henry yielded to the Spanish Inquisition, but wrote to them on the 5th of December to address a formal requisition on this subject, while the Inquisition of Evora would do the same to Cardinal Espinosa. The Supreme Council consented to this arrangement, and the prisoners were exchanged.
