This is the official steward decision report.
I am not sure which comes first, but I guess the yellow pages at the end of the PDF file.
There it says (on p5 and p6) for car 8 and car 19 respectively: cut chicane, without advantage.
p2 mentions: car 19 and 8 cut the chicane. car 19 gain advantage.
p1 gives hands out the penalty, and mentions the wrong driver name (Caldarelli instead of Perez Companc)
Hard to be impressed by all that.
(And then I haven't even complained that they can't spell the word chicane)
