Final answer:
The power to enforce eminent domain is held by the federal government, state governments, and local governments in the United States.
Step-by-step explanation:
The power to enforce eminent domain is held by multiple layers of government in the United States. Corporations, on the other hand, do not have this power in and of themselves; however, they can be the beneficiaries if a government entity uses eminent domain to transfer private property for public use, as seen in cases where such actions have been taken to facilitate economic development.
The Fifth Amendment to the United States Constitution mentions eminent domain under the Takings Clause, requiring that the property is used for "public use" and that "just compensation" is provided to the original owners. Conflicts arise when determining what constitutes 'public use,' which led to legal changes post the Kelo decision to restrict the use of eminent domain for economic development that primarily benefits private entities.
