The team were investigated under article 13.2(f) of the Sporting Regulations which requires teams to participate in every round of the championship.
Manor supplied a written explanation for their absence and further evidence was supplied by FIA technical delegate Jo Bauer.
The stewards ruled against bringing any sanction against the team on the grounds that the team had “attended the event, brought a significant quantity of material and equipment with it, produced all required documents for checking, taken part in scrutineering and its two cars were eligible to compete, brought sufficient staff to prepare the cars for competition, continued to work and do all within its ability to enable the two cars to compete and prepared the cars to a state where they were mechanically complete”.
The stewards added Manor “would not have been able to achieve a software configuration that allowed the two cars to then be operated in practice or qualifying session, even if they had worked outside curfew requirements”.
Manor had “used all reasonable endeavours to ensure that its cars were able to compete in active competition”, in the view of the stewards.
