Rule 56(c)(4) concerns which of the following?

• A. Rules regarding affidavits generally
• B. Rules for service of process
• C. Requirements for an affidavit
• D. Standards for summary judgment

Answer: (C)

Rule 56(c)(4) focuses on the form and content of affidavits or declarations used with a motion for summary judgment. It requires that any such affidavit be based on the affiant’s personal knowledge, set out facts admissible in evidence, and show that the affiant is competent to testify about the matters stated. If the affidavit relies on information and belief rather than personal knowledge, it must explain the sources and basis for that belief. These requirements ensure the evidence submitted to support or oppose summary judgment is reliable and testable in court. This is more specific than general rules about service of process or the overall standards for summary judgment; it’s about making sure the supporting affidavits themselves meet certain admissibility and reliability standards.
