The individual, aged 50, who has overseen Red Bull Racing since its establishment in 2005, will undergo questioning by an independent lawyer regarding the complaint.
The parent company, Red Bull GmbH, situated near Salzburg, Austria, stated on Monday that it is treating the accusations against Horner with utmost seriousness.
While the team has not officially disclosed the nature of the complaint against Horner.
Horner refuted the allegations in a statement to Dutch newspaper De Telegraaf and within an F1 Commission meeting involving team principals, the FIA, and F1 commercial rights holders earlier this week.
Since the allegations surfaced on Monday, speculation regarding Horner’s future has been rife within the F1 community.
Nonetheless, Horner wields significant power and influence, both within the Red Bull organization and the broader F1 community, casting uncertainty on whether these allegations will ultimately result in his downfall.
Regardless of the outcome of Friday’s hearing, considerable uncertainty surrounds the future of Red Bull.
Should Horner be ousted from his role, whether through termination or resignation, reports suggest that a replacement from the Austrian division of Red Bull would likely step in to fill the void.
