§ 1349 Arrest of party causing restraint.

Here's a plain English summary of this rule:

When a court is dealing with a case of someone being illegally held or restrained (this is called a habeas corpus case), the judge has an extra option available. Besides just ordering the person's release, the judge can also add a command to the warrant that orders the arrest of whoever caused the illegal restraint in the first place.

This means the judge doesn't just have to free the person who was wrongly held. If the judge thinks it's needed, they can also have the person responsible for the wrongful restraint taken into custody. This gives the court a way to hold someone accountable right away, instead of just fixing the immediate problem of freeing the person who was restrained.

The decision to add this arrest command is up to the judge. The rule says the judge can do this "if deemed necessary," which means it's not automatic. The judge looks at the situation and decides whether arresting the person who caused the restraint is the right move.
