The Rule was a ban of cellphones due to possible interference with hospital electronics.

The REMOVAL of the rule would be allowing cell phones to be used. (As is currently the practice. As evidence of this being the removal of a rule rather than creating a new rule, they simply removed the signs at our local hospital which advised people to turn off their cell phones. No new signs were posted)

Banning cellphones again would be REINSTATEMENT of a rule, not removal.
