Natural justice breach: non self contained, short notice show cause demands require reissuance with fair opportunity.
A show cause notice initiating an adjudicatory demand must be self contained, supply sufficient material for response, and afford a reasonable opportunity to reply; an inadequate content and an unreasonably short response period (well below the preferred thirty days and below a minimum of fifteen days) violate audi alteram partem and procedural fairness. Defective notices warrant issuance of a fresh, legally valid notice rectifying the procedural defects, and may attract costs consequences against the issuing authority.
