The Delaware Constitution, Section I, Bill of Rights, Section 8 says:
"Section 8. No person shall for any indictable offense be proceeded against criminally by information, except in cases arising in the land or naval forces, or in the militia when in actual service in time of war or public danger; and no person shall be for the same offense twice put in jeopardy of life or limb; nor shall any person's property be taken or applied to public use without the consent of his or her representatives, and without compensation being made."
The United States Constitution, Bill of Rights, Amendment 5 says:
Amendment 5 - Trial and Punishment, Compensation for Takings
"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."
The bold is my doing.
Under both the US Constitution and the Delaware Constitution it is illegal to "take" private property without paying just compensation for that property.
