Who is "part of Piscataway?"
It is the citizens of Piscataway. The citizens have authorized there elected city commissioners, alderman, whatever, to represent their interest.
It is obvious that these elected alderman feel no pressure from the citizens of Piscataway to stop this condemnation.
Don't castiage the judge. At minimum the U.S. Constitution, in the Bill of Rights, Amendment V, states, "...nor shall private property be taken for public use without just compensation." The judge is ruling within constitutional boundaries.
I presume the New Jersey Constitution has a similar amendment.
That being the case, the Halper's property has been declared needed for "public use" and the will be justly "compensated."
But the Halper's need to blame their fellow citizens for allowing their predicament. Their fellow citizens, through their silence, are telling the elected local alderman to use their tax money, compensate the Halper's, and make the propery into a public use area.
Halper's, appeal and get mad at your fellow citizens. They are the ones taking your property away.
