No compensation if similar restrictions in force under any other law or if any?

No compensation shall be awarded- (a) if and in so far as the land is subject to substantially similar restrictions in force under some other law which was in force on the date on which the restrictions were imposed by this Act; (b) if any compensation has already been paid in respect of same restrictions imposed under this Act or under any other law to the claimant or to any predecessor-in-title of the claimant for any period; (c) In case of payment of compensation for any alternate access on account of diversion of highway, where the right of access to a highway has been destroyed as a result of the diversion thereof and an alternative access has been given, the amount of compensation shall not exceed the cost of laying a new access from the area of the claimant to such alternative route.
