What term is used to describe a legally binding order for a person to appear at a specific time and place?

The correct term to describe a legally binding order for a person to appear at a specific time and place is "summons." A summons is an official document issued by a court or an authorized entity that compels an individual to attend court proceedings. It serves as a formal notification that a legal case involves the recipient and requires their presence.

The legal framework surrounding a summons typically ensures that the individual is informed of their responsibilities and the specific details regarding their required appearance. This process is vital for upholding the principles of due process, ensuring that individuals have the opportunity to respond to legal actions that may affect them.

Other terms in the choices provided do not carry the same legal significance as a summons. For instance, "notice" may refer to informing someone about a legal issue but does not imply the obligation of attending a legal proceeding. "Mandate" often pertains to an order or command but is typically associated with higher authorities, and may not be specifically directed at an individual's legal obligation to appear. "Proclamation" generally refers to an announcement or declaration made officially, which does not pertain to the individual obligations typically outlined in a summons.
