law: Indian Easements Act, 1882
  16. Exclusion in favor of reversioner of servant heritage
  Provided that, when any land upon, over or from which
  
  any easement has been enjoyed or derived has been held under or by virtue of
  
  any interest for life or any term of years exceeding three years from the
  
  granting thereof, the time of the enjoyment of such easement during the
  
  continuance of such interest or term shall be excluded in the computation of
  
  the said last-mentioned period of twenty years, in case the claim is, within
  
  three years next after the determination of such interest or term, resisted by
  
  the person entitled, on such determination, to the said land.
  Illustration
  A sues for a declaration that he is entitled to a right to way
  
  over B's land. A proves that he has enjoyed the right for twenty-five years;
  
  but B shows that during ten of these years C had a life- interest in the land;
  
  that on C’s death B became entitled to the land; and that within two years
  
  after C’s death he contested A’s claim to the right. The suit must be
  
  dismissed, as A, with reference to the provisions of this section, has only
  
  proved enjoyment for fifteen years.
