Logan files a diversity negligence suit after a warehouse injury. The state statute assigns the statutory-employee question to the judge while federal practice assigns it to the jury. The court weighs the state's interest in integrating the determination into its transportation liability scheme against the federal interest in preserving the civil jury's historic role and decides which rule governs.
Brighton Manufacturing obtains a permit and spends heavily on site preparation for a new plant. The city later rezones the area to prohibit the use. The court balances the company's good-faith expenditures and changed position against the municipality's interest in enforcing the new zoning to decide whether a vested right protects completion of the project.
Brittany Bell receives Social Security disability payments. The agency proposes termination after a file review and gives written notice plus an opportunity to respond in writing. The court weighs her interest in continued benefits and the risk of erroneous deprivation against the government's interest in efficient administration and concludes that the written procedures satisfy due process.
Boulder Construction owns a historic terminal and plans a modern addition that would increase revenue. The city designates the building a landmark and blocks the addition. The court weighs the economic impact and interference with investment-backed expectations against the character of the governmental action as historic preservation and determines whether a taking has occurred.
A federal court uses the test when no federal rule or statute directly addresses the issue and the substantive-procedural characterization is uncertain. The court then weighs the state's interest in its rule against the federal system's interest in its own practice to decide which governs.
The test weighs the private interest in continued benefits, the risk of erroneous deprivation, and the value of additional safeguards against the government's administrative and fiscal interests. Written notice and an opportunity to respond in writing before termination, followed by a later hearing, can satisfy due process when the balance favors the government.
The test considers the economic impact on the claimant, the extent of interference with distinct investment-backed expectations, and the character of the governmental action. Regulations that leave economically viable uses are generally upheld when these factors do not favor the owner.
Some jurisdictions require a valid permit and substantial construction. Others apply the balance of interests test directly to determine whether good-faith reliance and changed position make it inequitable to deprive the owner of the right to complete the use.
