Dispute between Govt & grantee over reserved rights goes to:

A dispute between the Government and a grantee concerning reserved rights is typically referred to the EDO (Revenue) or a similar senior revenue officer. These officers are empowered within the revenue administration to adjudicate and resolve such administrative disputes, acting as the primary authority for addressing grievances related to land grants and government rights.

• An Arbitrator is generally used for specific contractual disputes, not typically for statutory reserved rights disputes within the revenue framework.
• The BoR (Board of Revenue) is a higher authority, but the EDO (Revenue) or Commissioner is usually the initial point of contact for resolving such disputes.
• The Chief Justice is a judicial position and is not involved in the initial administrative resolution of land disputes.
