After looking at statements he [Prucka] made in a deposition, it seems pretty clear he just didn’t like the idea of ramps and widening halls and did not want his house to be used by his neighbor’s disabled daughter.
The neighbor--Anthony Petrello--has literally made this a federal case, filing a federal lawsuit against Prucka. Both lawsuits (Petrello's and the city's) allege that Prucka is guilty of discrimination against the neighbor's disabled daughter--the house was to be used to house medical personnel who care for the daughter.
This entire issue boils down to a situation with a willing buyer and an unwilling seller. For whatever reason, Prucka did not want to sell his home to Petrello. His reason may be perfectly rational and valid, or it may be completely irrational. In either case, it doesn't matter. It is his choice.
That the city is involved in this illustrates how meddling the local government is becoming. The government's proper function is the protection of individual rights. It should not be in the business of forcing individuals to sell their property against their own judgment.
In this particular case, Petrello desired to purchase a property, but Prucka did not desire to sell it to him. Prucka's property rights allow him to choose the conditions under which he will sell his property, and those conditions may be appropriate and valid, or they may be silly and bizarre. That is Prucka's right and his prerogative. If Petrello does not like the conditions, he can simply refuse to close the deal.
Petrello refuses to recognize Prucka's rights. Petrello seeks to force Prucka to sell his home, contrary to his own judgment and against his own desires. And by siding with Petrello, the city is demonstrating that it has no regard for individual rights.
Anti-discrimination laws are inherently irrational and a violation of individual rights. Such laws prohibit individuals from acting according to their own judgment. Such laws force individuals to act according to values that they may not embrace. Such laws should be abolished, and the city should drop its lawsuit.
If the city is truly interested in "fair" housing it should quit regulating land-use and repeal all building codes. Indeed, if the city wants "fairness" in any realm, it should be protecting individual rights. There can be no "fairness" without individual rights. Without individual rights, society becomes a battle over the use of government power for the purpose of dispensing favors and punishing the recalcitrant.
