Port-Starboard and a Wind Shift

Rules Quiz - Port Starboard with a windshift

Boats S (blue, on starboard tack) and P (yellow, on port tack) are both sailing close-hauled and are converging on a beat.  P will safely cross S.  However, when they are less than 2 boat-lengths apart, the wind shifts to the right ten degrees.  S heads up (changes her course) in response to the windshift such that P is unable to keep clear.  There is minor contact with no damage or injury, and both boats protest.  You are on the protest committee.  How would you decide this and why?
