What is the meaning of 'Call On' in a civil court case? Can you explain what 'call on' means in cour

In court, the term "call on"generally means that a case is scheduled for hearing on a specific date, or that a person is being summoned to give evidence. When a case is "called on"or shown as "call on date"in court records or e-court systems, it means the matter is officially listed before the court. On that day, the case will be announced (usually by the court clerk), and the parties involved the plaintiff, defendant, and their lawyers are expected to be present. Depending on the stage of the case, the court may hear arguments, review evidence, check progress, or issue further directions.
"Call on"can also mean summoning a person to appear in court, usually to give evidence or produce documents. For example, a witness may be "called on"to testify, or even one of the parties to the case may be directed by the court to step forward and provide evidence. If someone refuses without a valid reason, the court may even pass orders against them. Under CrPC Section 311, the court has the power to summon a material witness or recall/examine someone if their testimony is essential for justice.
