Liberty Media, the parent company of Formula 1, has asked the court for permission to make a limited appearance in NASCAR's antitrust lawsuit. The move is aimed at protecting confidential information that surfaced during the case's discovery process.The organisation apparently shared information with 23XI Racing regarding their Concorde agreement, which contains sensitive data involving F1, FIA and the teams themselves. Liberty Media maintains that it cooperated with subpoenas but shared information under strict terms of confidentiality.As per the company, unsealing the documents without redactions could expose proprietary Formula 1 material to the public. Therefore, they've asked for an attorney to be present during the trial process to make sure it doesn't happen. The corporation has also reassured that its involvement will not slow the proceedings or affect the December 1 trial date.NASCAR reporter Matt Weaver shared F1's involvement on X. An excerpt from the filing read:"While Liberty Media has no direct interest in the merits or ultimate disposition of the underlying action, it has a significant interest in protecting non-public information from the Concorde Agreement and preventing such material from being subject to public dissemination through unsealing of exhibits to various filings in this action.""Liberty Media's intervention in this action would be for the sole and limited purpose of seeking the Court's permission to redact or otherwise protect the highly sensitive information contained in the Wendling Declaration and related expert reports."NASCAR recently faced a setback in the antitrust lawsuit against 23XI and Front Row Motorsports. The court dismissed its counterclaim against the team's summary motion, which demarkates the sancitoning body as a 'premier stock racing series'.Judge Kenneth Bell ruled in the teams' favour and granted them the summary motion as well. Its now upto the two teams to prove that NASCAR used this power to influence the 2025 charter deal.23XI and FRM drop a clause in their lawsuit against NASCAR23XI and FRM have asked the court for a partial dismissal of their antitrust case. The team apparently want to remove the clause targeting International Speedway Corporation's involvement in controlling the racing market.The case will now focus on the santioning body alone, as Fox analyst Bob Pockrass shared,“Think of it this way: Section 1 more would cover NASCAR and ISC working together to monopolize a market. Section 2 covers one company's unilateral acts. That has always been strongest part of case so better to focus on that at trial.”The lawsuit is based on the Sherman Antitrust Act, which prohibits monopolistic practices. If the governing body lose the case, a majory overhaul of the hcarter system is expected.The two teams, however, aren’t focused on the charter system itself, but on the charter deal that hands them a smaller slice of the new $7.7 billion media rights package.
