He needed to show that he did not alienate the property because alienation of property of that value requires the consent of both the diocesan finance council and the college of consultors. In fact, Archbishop Balvo, who at the time was the Apostolic Delegate, wrote Apuron on March 7, 2012, reminding him of this:
Regarding the matter at hand, as indicated in the various paragraphs of Canon 1292, to carry out acts of alienation, consent is required not only from the diocesan finance council but also of the college of consultors. If these do not give their consent, the diocesan bishop is not free to do as he pleases.
According to Canon 1295, the consent of the same bodies is required in any transaction which can worse the patrimonial condition of the diocese.
Can. 1296 When alienation has taken place without-the prescribed canonical formalities, but is valid in civil law, the competent authority must carefully weigh all the circumstances and decide whether, and if so what, action is to be taken, namely personal or real, by whom and against whom, to vindicate the rights of the Church.
