State constituencies
Section 112 · 1999 Constitution (2004 edition)
What Constitution says
Subject to the provisions of sections 91 and 113 of this Constitution, the Independent National Electoral Commission shall divide every state in the federation into such number of state constituencies as is equal to three or four times the number of Federal constituencies within that state.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
