If there was any short coming in the Exhibit F, that made it to fail to comply with the adoption laws of Eastern Nigeria, as alleged by the Appellants, that cannot, in my opinion, be the fault of the Respondent or his adoptors, Aduba and his wife, and would not discount from the presumption of its regularity as official Government instrument, authorizing the acceptance and adoption of the Respondent into the home of Mr. and Mrs. Aduba Nwaemere as a member of their family. In the eye of the law, the presumption of regularity of official act remains strong (See section 168 of the Evidence Act 2011), and so is Exhibit F presumed in favour of the Respondent. Again, equity looks as done, that which ought to be done.
