Mike I'm just going by what is in the article, specifically this paragraph:
Dixon “has now been entirely deprived of his livelihood and sole source of income by this unjustifiable suspension—which is, in effect, a lifetime ban from NHRA—unless he relinquishes an investment of hundreds of thousands of dollars, as well as the future profits that he could derive from that investment,” according to the complaint.
It sounds like the ban was lifted with conditions, which is why I made my statement that what he does as a business venture should not impact his ability to be licensed and drive a certified car at NHRA national events.
