Alteration of memorandum requires court-directed notice, publication and service, providing a formal hearing opportunity for affected parties. The court may order that a petition to alter a company's memorandum be posted for hearing, require publication of notices in specified newspapers, and prescribe that interested persons give written notice of objections to the petitioner's advocate with stated grounds. The order also directs service of the petition and hearing date on the Registrar of Companies and, where applicable, the Central Government, and contemplates notice to debenture holders and creditors meeting a prescribed claim threshold.
