The duty of every appellant is to show and or establish that the decision he has appealed was wrong or unreasonable. Every decision of a Court of law, a judicial act, done in a manner substantially regular is presumed to be correct and that formal requisites for its validity were complied with. The presumption of regularity under Section 167(1) of the Evidence Act, 2011 is all about this.
