Welsh Petanque Association

Boule 1 is duely marked and nearest the jack
Boule 2 is unmarked and lying second.

A boule comes in from another piste and hits both boule 1 and boule 2. Both boules move to a position where boule 1 is still closest. However if boule 1 is moved back to its marked position, boule 2 would now be scoring (can't be moved back as it was unmarked).  

Do all marked boules have to be replaced.
Can Team 1 insist that team 2 mark their boules?
Can team1 mark team 2’s boule?
