Final answer:
The time to respond to an IDM's request can vary and is usually defined by the contract or by the IDM if not specified; parties should review contract documents or IDM guidelines to determine the precise time frame.
Step-by-step explanation:
When an IDM (Independent Dispute Manager) requests a party to provide a response to a claim or to furnish additional supporting data, the time frame to respond can vary based on the specific rules of the procedure, the jurisdiction, or the terms of the contract in question. Typically, contracts with IDM provisions should outline the specific time allowed for responses. If there is no specified time frame in the contract, the IDM will usually set a reasonable deadline. It's crucial for parties to review the contract documents or guidelines provided by the IDM to determine the exact time allowed. Failure to respond within the allotted time may have implications on the resolution of the dispute.
