Why couldn't the mining company object to the homeowner's disclosure of deposition testimony?

The reason the mining company could not object to the homeowner's disclosure of deposition testimony is that the objection was not filed within the required time frame. In civil procedure, there are specific timelines established for raising objections related to discovery. If a party fails to file an objection by the deadline set by the rules or court orders, they typically waive their right to contest the disclosure or use of that evidence in the case. Therefore, time-sensitive rules regarding objections play a crucial role in ensuring that all parties are aware of and can respond to issues as they arise during the discovery process. This procedural requirement helps maintain the efficiency and effectiveness of the judicial process.
