Irregularity, disorder, departure from rule. By (English) R.S.C. 1883, Ord. LXX., non-compliance with the rules renders proceedings liable to be set aside as irregular, but does not render them void unless the Court or a judge so direct. Order LIV., r. 24, of the (English) County Court Rules, 1903, is to the same effect.
The word 'irregularity' in common English parlance means and implies contrary to rule, Rambhau v. State of Maharashtra, AIR 2001 SC 2120 (2122): (2001) 4 SCC 759. (Cr. P.C., 1973, s. 391)
The word irregularity' in s. 131(2)(b) cannot be confined to procedural defects only, Martin Burn Ltd. v. Corporation of Calcutta, AIR 1966 SC 529 (534): (1966) 1 SCR 543. [Calcutta Municipal Act, 1923 (3 of 1923), s. 131(2)(b)]
