Which rule states the conditions for subpoena issuance for depositions?

The correct answer is B, as Rule 45.1 specifically outlines the procedures and conditions for issuing subpoenas for depositions. This rule provides guidelines on how parties can compel witnesses to attend and testify during depositions, ensuring that due process is observed while respecting the rights of the individuals being subpoenaed. It details the requirements for issuing a subpoena, including the necessary information that must be included, such as the time and place of the deposition and the scope of testimony expected.

Understanding this rule is crucial for a process server, as it impacts how they serve subpoenas and ensures that all procedural requirements are met, thereby maintaining the integrity of the legal process and minimizing potential conflicts or objections from witnesses. By adhering to the specifications set forth in Rule 45.1, process servers can effectively facilitate the deposition process, which is an essential aspect of preparing for trial.
