A huge chunk of the federal judiciary are white supremacists.

There is your problem.
However Byron I dont think had a case to begin with.
Basically contract talks broke down and he felt racial animus was involved
I am not sure if he ever proved his case legitimately. I feel like he just threw money at the situation and used the (hate this word) "race card" in a broader public display.
He has never been down for black people so its hard to see a good angle for him here
Allen filed a lawsuit (filed under both Allen's National Association of African-American-Owned Media and Entertainment Studios) in the
United States District Court for the Central District of California against Comcast in February 2015, seeking US$20 billion in damages and citing that Comcast had used racial discrimination to deny him a contract, in violation of section 1981 of the
Civil Rights Act of 1866.
[2] Allen alleged that Comcast was discriminating against 100%-minority owned networks like Entertainment Studios, as only US$3 million of the total US$11 billion carriage fees Comcast paid were to 100%-minority owned networks. Comcast refuted the accusations, stating they had been in negotiations with Allen in good faith for several years to strike a deal.
[3] Comcast claimed that the lawsuit was "an ordinary business grievance masquerading as a racial discrimination claim".
