Yes, the definition section of 3101 defines a Private Way as a public easement as defined in 3021, ss 2, which in turn means certain easements held by a municipality.
This, however, is just a definition of a particular term. It does not mean that the Private Ways statute only applies to those municipal easements, though.
If you look at 3101 subsection 2, you'll find:
When 4 or more parcels of land are benefited by a private road, private way or bridge as an easement or by fee ownership of the private road, private way or bridge, the owners of any 3 or more of the parcels, as long as at least 3 of the parcels are owned by different persons, may make written application to a notary public to call a meeting.
That is, the law applies to private roads and private bridges as well as private ways.
An easement is an interest in the use of real property owned by someone else. For instance, power companies typically have an easement which permit them to install and maintain power lines that pass over the property of others.
A right-of-way is a particular type of easement which grants the right to pass over another's property for some reason, such as access to your own property. So, whenever you see the word easement, your right-of-way is qualifies as one.
I help this helps.
