Manorial Waste

[Budlet]

The village where I live has a strip of land classed as manorial waste (definition: manorial waste is part of the demesne of a manor left uncultivated and unenclosed, over which the freehold and customary tenant might have rights of common). The owner of the house at one edge of this land wants to extend his property over part of the manorial waste land. Are the Council allowed to grant permission for this (I view it as a land grab) as it will surely open the floodgates for other residents to grab parcels of this land?
Thanks for your responses in advance.

I'd not know but suspect people can grab whatever others allow them to, and after a time it is granted them. Seems to work that way.
