The expansion of the Bill of Rights changed due process into substantive due process, including broad protection to property rights. The Bill of Rights serves as an essential protection for individuals from the undue oppressions of the government. Originally, the Bill of Rights
only applied to the federal government, not state governments. But it
was gradually incorporated to state government through the process of
incorporation. This “incorporation” is used to legally allow the gradual
application of the Bill of Rights to protect everyone from the federal as well as the state government.
