The Undang of Johol, three other Undang whose legitimacy remains contested, and the Tunku Besar Tampin have jointly issued a statement urging all parties, including the Prime Minister and the Attorney General, to refrain from intervening in the administrative affairs of Negri Sembilan. The group emphasized their customary rights, grounded in the 1959 Laws of the Constitution of Negri Sembilan, which grant them the authority to appoint or remove the Yang di-Pertuan Besar, the state's monarch.

According to the statement, allegations suggesting that Mentri Besar Datuk Ismail Lasim and his executive council (exco) orchestrated the dethronement of Tuanku Muhriz Tuanku Munawir are unfounded and constitute malicious slander intended to serve the interests of specific factions. The chiefs clarified that the Mentri Besar and his exco possess no independent authority on such matters but are responsible solely for implementing decisions made by the chiefs, who function as co-rulers (Raja Pemerintah) under state law.

The chiefs also asserted that neither the Prime Minister nor the Attorney General has jurisdiction over the internal administrative matters of Negri Sembilan, warning that any unconstitutional interference could breach the Prime Minister’s oath under the Sixth Schedule as well as Article 71 of the Federal Constitution. They further urged those unfamiliar with the state’s Malay customs (adat) and governance, including members of the Opposition, to cease issuing statements or criticisms they described as misguided or misleading against the state's customary institutions.

In addition, the group challenged the legitimacy of a recent decision by Tuanku Muhriz to dismiss the state exco, labeling it unconstitutional and unprecedented in Negri Sembilan’s modern history. They argued that any removal or appointment of executive council members must be based on the advice of the Mentri Besar and the state exco.

The chiefs also claimed that Tuanku Muhriz had been officially deposed according to Article 10(1) and (2) of the state laws on April 19, with a formal proclamation signed by the Mentri Besar on August 3. The developments have sparked significant controversy within the state, underscoring ongoing disputes over the exercise of constitutional and customary authority in Negri Sembilan.
