M"B 25:42 makes it clear that we always follow Gemara over Zohar. And we similarly follow Bavli over Yerushalmi (as is clear from the Hirhurim article quoted in this related discussion).
However, do we follow Zohar or Yerushalmi?
According to Harav Yishak Yosef Shelit"a (En Yishak vol. 1 pg. 334) we follow the Yerushalmi over the Zohar.
