Section 3J expressly excludes the application of the Land Acquisition Act, 1894 for any acquisitions under this act (National Highways).
Section 3C of the National Highways Act allows for hearing of objections. It provides that objects can be filed in writing and the grounds of objection within 21 days of the publication of notification under sec 3A. Order of the competant authority is final.
The compensation shall be decided by an order of the competant authority who is appointed by the Central Government. Section 3G governs the determination of amount payable as compensation. Among other provisions it includes that in case the amount of compensation is not acceptable, it will be decided by an arbitrator appointed by the central government. Section 3G(7) governs the factors to be considered while determining compensation.
I might be wrong but I dont see any provision for 'land' compensation. Maybe Learned members would have some examples from experience.
