Hearing without production of person.

When, from the sickness or infirmity of the person directed to be produced, that person cannot without danger be brought before the court, the person in whose custody or power that person is may state that fact in the return to the writ. If the court is satisfied of the truth of the return and the return is otherwise sufficient, the court shall proceed to decide on the return and to dispose of the matter as if the party had been produced.
