Section 119(1) says the Court "may presume" the existence of any fact it thinks likely to have happened, and illustration (e) lists that judicial and official acts have been regularly performed. Under section 2(1)(h) the Court may then treat the fact as proved unless disproved or call for proof of it, and it must consider the facts of the particular case. The presumption is neither compulsory nor conclusive, and it covers official as well as judicial acts.
