In the case of PEENOK INVESTMENTS LTD. v. HOTEL PRESIDENTIAL (1982) 12 SC (REPRINT) the Supreme Court per A.G. IRIKEFE JSC stated that as a general proposition of law, foreign law is a question of fact which should be pleaded and proved in a trial Court.
PLEADINGS SHOULD NOT CONTAIN LAW OR MIXED LAW & FACT
It is well settled that every pleading must state facts and not law. A party is not expected to plead conclusions of law or mixed fact and law. However, conclusions of law can be drawn from material facts pleaded. It is also unnecessary to set out in a pleading content of a public statute.
