looks like it was both:

The NBA had all along suspected an illegal deal with Mourning--which it could not prove despite an investigation--after the trade from Charlotte last year. Mourning had implied on ESPN that he had a deal, though he never said he did. But he knew after turning down Charlotte's offer he'd get at least $100 million from Miami. The league ruled that constituted a deal and added his new salary to the Heat's cap, eventually causing the signing's cancellation.
But in the interim, Howard agreed to the Heat's $100 million offer and the Bullets renounced their rights to him and signed free agents Tracy Murray and Lorenzo Williams, under salary rules preventing them from re-signing Howard.
The Heat then added free agents P.J. Brown and Tim Hardaway, writing in incentives for 45- and 43-victory seasons. That opened up another issue since incentives count against the cap only if they are ones that have been achieved previously, such as a most valuable player bonus for Jordan. The Heat noted the team high for wins was 42, so those figures had never been achieved. The league said the signings assured a better season, so they were counted against the cap, leaving even less room for Howard.
His signing was overturned in combination with the judgment on Mourning's "deal."
