Right to peaceful assembly and association
Section 40 · 1999 Constitution (2004 edition)
What Constitution says
Every person shall be entitled to assemble freely and associate with other persons, and in particular he may form or belong to any political party, trade union or any other association for the protection of his interests: Provided that the provisions of this section shall not derogate from the powers conferred by this Constitution on the Independent National Electoral Commission with respect to political parties to which that Commission does not accord recognition.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
