An affidavit meant for use in court stands as evidence and must as near as possible conform to oral evidence admissible in court. Sections 86 and 87 of the Evidence Act provide as follows:- “86. Every affidavit used in the court shall contain only a statement of facts and circumstances to which the witness deposes, either of his own personal knowledge or from information which he believes to be true. 87. An affidavit shall not contain extraneous matter, by way of objection, or prayer, or legal argument or conclusion.” … Looking at the counter-affidavit, paragraphs 12, 13 and 14 are fit for Counsel to urge upon the court by way of submission and, if there are facts and circumstances presented in support, the court may consider the submission attractive enough to dissuade it from granting the bail sought. Paragraph 18 contains a conclusion which ought to be left to the court to reach. Therefore paragraphs 12, 13, 14 and 18 are extraneous being in contravention of Section 87 of the Evidence Act. They ought to have been struck out. I accordingly strike them out. As for the further counter-affidavit, paragraphs 9, 10, 11, 12, 13 and 18 are also extraneous because they are fit for argument of Counsel to persuade the court. I strike them out as well.
