Duomatic principle upheld: unanimous member acquiescence prevents oppression or mismanagement findings in family company governance dispute.
The Duomatic Principle was applied to validate informal corporate acts where members gave unanimous or tacit assent: a director's withdrawal of resignation, the appointment of a managing director, and share transfers were held bona fide and not fraudulent. The appellant's prior knowledge and acquiescence estopped subsequent challenges, and she lacked locus to sue on behalf of trusts. Fraud remains an exception to Duomatic application; absent fraud and public prejudice, the facts did not constitute oppression or mismanagement.

Duomatic principle: unanimous member assent can validate informal corporate acts and bar oppression claims without fraud.
The Duomatic Principle validates informal corporate acts effected with unanimous or tacit member assent, permitting departure from strict statutory formalities where transactions are bona fide and free from fraud. Prior knowledge, acquiescence and estoppel by a complainant can negate claims of oppression or mismanagement arising from appointments, withdrawal of resignations, share transmissions, and conduct of meetings, preserving corporate finality and internal decision-making.
