My co-shareholder in Kolkata has violated the shareholders agreement by issuing additional shares without my consent; how can I enforce my rights?

You can enforce the shareholders agreement by filing a suit for specific performance and injunction to restrain the further issuance of shares in violation of the pre-emptive rights or anti-dilution clauses. If the agreement contains an arbitration clause, you must initiate arbitration under the Arbitration and Conciliation Act, 1996. You may also approach the NCLT under Sections 241-242 of the Companies Act, 2013, for oppression and mismanagement if the share issuance prejudices your rights. The Calcutta High Court may be approached for interim relief pending arbitration or NCLT proceedings. The West Bengal Premises Tenancy Act 1997 on contract enforcement and the Specific Relief Act, 1963, are relevant to your claim. Documenting the breach and the financial impact on your shareholding is crucial.
