In this situation, the supplier may not have a legal right to claim the 75% payment based solely on the clause that states payment is due upon the machine's arrival at the site. Since the machine is defective and not functioning, your company has a legitimate reason to withhold payment. Generally, contracts imply that goods delivered should be of satisfactory quality and fit for purpose. If the machine does not meet these standards, it could be considered a breach of contract by the supplier.
Regarding legal steps your company can take against the supplier for providing defective machinery, here are some options:
1. Send a Formal Notice: Draft a formal letter to the supplier outlining the defects of the machine, your refusal to pay, and request for rectification or replacement. This serves as a written record of your complaint.
2. Negotiate: Engage in discussions with the supplier to resolve the issue amicably. You can propose a remedy, such as repairing the machine or replacing it with a functioning one.
3. Invoke Contractual Remedies: If the contract includes specific clauses regarding defects, warranty, or performance, you can invoke those clauses to seek remedies.
4. File a Complaint: If negotiations fail, you may consider filing a complaint with the relevant consumer forum or regulatory authority, depending on the nature of the contract and the parties involved.
5. Legal Action: As a last resort, you could initiate legal proceedings against the supplier for breach of contract, seeking damages or specific performance.
It's advisable to consult with a legal professional to assess your specific situation and determine the best course of action based on the contract terms and applicable laws.
