SCOTUS denied the petition, so they won't be hearing the case.
The Third Circuit's opinion can be read
here. The gist is that Revell sued the Ports Authority and one of its police officers under the federal Firearm Owners’ Protection Act ("FOPA"), which allows gun owners licensed in one state to carry firearms through another state under certain circumstances. Among these circumstances is that the owner of the gun does not have ready access to the gun while in transit. The Third Circuit ruled that when he took his luggage (including the gun) with him to the hotel, he had ready access to it, so he did not meet the requirements of FOPA. The court stated:
Although we conclude that Revell fell outside of [FOPA's] protection during his stay in New Jersey, we recognize that he had been placed in a difficult predicament through no fault of his own. However, [FOPA] clearly requires the traveler to part ways with his weapon and ammunition during travel; it does not address this type of interrupted journey or what the traveler is to do in this situation. Stranded gun owners like Revell have the option of going to law enforcement representatives at an airport or to airport personnel before they retrieve their luggage. The careful owner will do so and explain his situation, requesting that his firearm and ammunition be held for him overnight. While this no doubt adds to the inconvenience imposed upon the unfortunate traveler when his transportation plans go awry, it offers a reasonable means for a responsible gun owner to maintain the protection of [FOPA] and prevent unexpected exposure to state and local gun regulations.

The Court also ruled that Revell could not sue in federal court for damages resulting from the Ports Authority's failure to return his property because New Jersey law provided adequate remedies for him in that regard and he failed to take advantage of those adequate remedies. That's pretty basic.
