"With April Fool's Day only a few days away, we need to repeat our annual reminder that broadcasters need to be careful with any on-air pranks, jokes or other jokes prepared especially for the day. While a little fun is OK, remember that the FCC does have a rule against on-air hoaxes - and, of any day in the year, April 1 is the day that the broadcaster is most at risk. The FCC's rule against broadcast hoaxes, Section 73.1217 of the Commission's Rules, prevents stations from running any information about a "crime or catastrophe" on the air, if the broadcaster (1) knows the information to be false, (2) it is reasonably foreseeable that the broadcast of the material will cause substantial public harm and (3) public harm is in fact caused. Public harm is defined as "direct and actual damage to property or to the health or safety of the general public, or diversion of law enforcement or other public health and safety authorities from their duties." Air a program deemed a hoax, and expect to be fined by the FCC."
