"The stewards of the 2019 Canadian Grand Prix request that team representatives attend a hearing on Friday 21 June at 14:15 in the F1 Stewards Room, to hear a request from the entrant of Car 5, Scuderia Ferrari, to review the decision in Document 42 of that event," reads the summons issued at 11:30 this morning.
Today's summons was issued by the stewards at the Montreal event, though it is unclear at this time whether they will personally attend the hearing.
Ferrari has yet to reveal what new evidence it might have that could cause the stewards to change their decision, only that it is "significant".
It is understood that Vettel is also due to give evidence.
