foundation cripple wall studs and not the cripple studs above or below a
window. Therefore, this situation would be satisfactory per code.
I do not know the history of the code but I believe there are more
restrictive requirements on foundation cripple walls because (at least is
heavy seismic zones) buildings have a tendency to "slip" off their
foundation if they are not well supported. And even though it is possible
to cut a stud to short lengths, it is unlikely that a framer will do this
properly with no splits and studs flush to the sill and top plates.

Ralph,
I don't have any answer to your question, but I was thinking: What about the
studs between a double top plate and a header? They are generally less than
14" high, so it would seem to be this is contrary to the code requirement.
