@Michael915 So, either party has 14 days to write a review.
Neither can see see what the other wrote, UNTIL the 14 days are up (and there is no more opportunity to write a review) OR until both parties have completed their review
In other words if either writes a review at any point within the 14 days then it WILL be published at the 14 day mark regardless of what the other party does. BUT if both parties write their reviews THEN the review will be published immediately upon completion of the second review regardless of where it falls within that 14 day window.
There is no way to stop another party's review of you. Both have equal opportunity to review the other.
