The San Diego Parachute  Club practiced their parachute exercises every weekend, and usually they  did so in the air space approaching the San Diego, California,  international airport.
The airport management never objected to  the parachute club, but asked the Federal Aviation Agency (FAA) to block  the parachuting in the airport air space.
The FAA issued an Administrative Rule that did not require publication that prohibited the parachuting in the air space.
The  San Diego Parachute Club immediately challenged the rule saying it  should have been a Substantive Rule that had to be published, and giving  them the opportunity to protest the rule.
The FAA agreed and  published the Substantive Rule in the Federal Register; The San Diego  Parachute Club filed a written objection.
Consider the rights the San Diego Parachute Club have going forward.
What are their initial rights in protesting the FAA Substantive Rule forbidding their parachuting at the San Diego Airport?
What additional rights can they pursue if the FAA continues to move forward on the restriction?
Include the details of the parachute club's rights to protest all the way into the Federal Court System?
