According to Article 17 of the Constitution of Pakistan, every Pakistani has a birthright to make a political party or to join any political party of his choice. Moreover, every citizen of Pakistan can form associations or unions, such as trade union, labor union, etc.

We can see that this freedom is widely exercised by the public in one form or another. For example, many citizens are vocal supporters of their favorite political party. Almost every factory worker is part of a labor union. Almost every businessman is a member of a trade association. Lawyers have their bar associations, too. On top of that, those interested in leading the masses have registered their own political parties.

The government can impose some reasonable restrictions on the exercise of this right, keeping in view the security and well-being of Pakistan and its citizens. E.g. It can ban terrorist organizations, and it can ban rallies if there is threat of lawlessness, etc.
