[5] Decreto n.° 11:737 bearing the date of 17 Jun 1926 was published in Diário do Govêrno, I Série, No. 130, 19 Jun 1926. Contrary to legal practice, it was not issued under the authority of Govêrno da República Portuguesa being simply signed by nine ministers and stating that Mendes Cabeçadas ceased to exercise the functions of President of the Ministry and Minister of the Interior and that Gomes da Costa was appointed as a new President of the Ministry and Interim Minister of the Interior. Decreto n.° 11:738 (same dates and source) issued under the authority of Govêrno da República Portuguesa and signed solely by Gomes da Costa formally relieved Cabeçadas of his duties and confirmed the appointment of Gomes da Costa. Prior to the promulgation of both decrees in the Diário do Govêrno (19 Jun 1926) and their legal enactment, Gomes da Costa started to perform the functions of office by appointing António Claro as Minister of the Interior (decree n.° 11:739, dated 18 Jun 1926, published in Diário do Govêrno, I Série, No. 130, Sábado 19 Jun 1926).
