TRIPOLI (Reuters) - Libya's General National Council assembly (GNC) voted on Wednesday to make Islamic Sharia law the base for all legislation and for all state institutions, a decision that may impact banking, criminal and financial law.

"Islamic law is the source of legislation in Libya," the GNC said in a statement after the vote. "All state institutions need to comply with this."

The immediate scope of the decision was not clear, but a special committee would review all existing laws to guarantee they comply with Sharia.
