With profound respect to the erudite senior counsel, this cannot be. As this Court explained, in a most magisterial manner, the term irregularity in respect of procedure, is often construed to denote something that does not fundamentally taint or besmirch a procedure as to render it invalid or a nullity. In other words, an irregularity is deemed to be curable. However, personal service of an originating process, like a Notice of Appeal, is a fundamental requirement of the law.
