'The time when the administrative litigation commences will normally be based on the procedural requirements imposed by the relevant legislation, or the 'rules' of natural justice if no legislation exists, under which the administrative litigaton will be brought." Examples include the receipt of a complaint by the Competition Commissioner; and the receipt of an appeal by the Tax Court registrar. Where there is no specific statutory procedure, the litigation will be considered to have commenced when the board etc. is made aware of the complainant's intentions. "Documentation such as copies of agreements, requests for advisory, professional or consulting services, the supplier's accounting records, demand letters, copies of objections or appeals, etc., would usually indicate the purpose or objective of the service rendered in relation to civil or administrative proceedings."
