Public Nuisance Dispute Mediation Act Enforcement Rules Article 12

When the conditions referred to in Article 17 of this Act apply to a mediation committee member without that member recusing him or herself, or when there are sufficient facts causing concern that the member would be biased in the execution of his or her duties, the chairman shall, pursuant to his or her authority or an application from a party to the dispute, take the decision to excuse that member.
