Formula One (F1) stewards summoned Red Bull team boss Christian Horner after the Qatar Grand Prix on Sunday for an alleged breach of the governing FIA's international sporting code.
The summons cited articles 12.2.1 (f) and 12.2.1 (k) without providing further details.
The first article covers "any words, deeds or writings that have caused moral injury or loss to the FIA, its bodies, its members or its executive officers, and more generally on the interest of motor sport and on the values defended by the FIA".
The second relates to any misconduct towards licence-holders, officials, officers or member of the staff of the FIA, the organiser or promoter, competitors or doping control officials.
