What happens if you scratch and foul in the same turn in 8-ball?
The the first foul that occurs should be the called foul.
Under BCA and APA 8 Ball rules, multiple fouls, which can
include a scratch, cannot be assessed and only one foul can be
called.
Except on the break, a scratch is defined as a type of foul. The
shot must be a legal shot to foul, and if the break is not a legal
break, no foul can occur although a scratch can occur.
