Formation and promotion of an illegal association refers to the process of establishing and publicizing a group or organization that operates outside the boundaries of the law.

Formation of an illegal association involves the creation of a group that engages in activities that are deemed illegal by the law of the land. This could include criminal activities such as drug trafficking, human trafficking, terrorism, organized crime, or any other unlawful actions. The formation of such associations often involves individuals with shared interests in pursuing illegal activities coming together to establish a structured organization.

Promotion of an illegal association involves the activities undertaken to publicize and attract members to the group. This could involve recruitment efforts, propaganda campaigns, online promotion, or other means of spreading awareness about the illegal association. The promotion aims to attract like-minded individuals who are willing to participate in the illegal activities conducted by the association.

Both the formation and promotion of an illegal association are illegal acts themselves, as they involve the establishment and publicizing of a group that is engaged in criminal or unlawful activities. Law enforcement agencies work to identify and dismantle such associations to maintain law and order and protect public safety.
