Do you know what you're talking about?  Are "beneficial rights" something like "sacerdotal rites"?  They widened the road, he gets to use it like everyone else, is that a beneficial right?  What would be the opposite, a detrimental wrong?  "I can't grow corn there anymore, I have been detrimentally wronged."  In any case, buy me a bottle of Springbank sometime and I'll tell you how I fought the city for a $1,000 water-line easement because they were playing high and mighty and didn't ask my client first.  (She didn't know she had inherited it and no longer owned the property itself, but would have given it away for free if they hadn't been so nasty.)
