Peter Sauers v. Township of Lower Southampton, Pennsylvania

When the Township granted a variance that effectively changed a neighboring property's zoning from "C2 Heavy Commercial" to "R2 -Residential" - without first notifying him, did it deprive Appellant of rights secured by the United States Constitution, i.e., his right to substantive and procedural due process under the Fourteenth Amendment to the United States Constitution, his right to equal protection of the laws under the Fourteenth Amendment to the United States Constitution, his right under the Fifth Amendment to not be deprived of property without due process of law, and his right under the Fifth Amendment to not have his property taken for public use without just compensation?
