Right to apply for relief against oppression and mismanagement: qualifying members may petition, with tribunal able to waive thresholds. Section 244 sets out the right to apply under section 241 by identifying membership and shareholding thresholds for companies with and without share capital, requires applicants to have paid all calls due on their shares, treats joint holders as one member for counting purposes, allows the Tribunal to waive threshold requirements, and permits qualifying members to apply on behalf of others with their written consent.
