As it says on the tin.
Were the stewards justified in penalising LH?
Personally I don't think they were.
They were both fighting for position approaching the corner.
KR squeezed LH off the track and he had little choice but to cut the chicane otherwise there would have been a collision.
LH then rightly backed off and allowed KR to get in front before passing around the back of his car and overtaking him at the next corner.
Even Charlie Whiting judged it to be within the rules after Ron D queried it with him during the race.
