        capricious, or an abuse of power, nor unduly oppressive on individuals
    B.  Eminent Domain: takings must be for public purpose and government 
        must provide "Just compensation" to the owner of the property 
        interests it appropriates.
    C.  Regulatory Takings
        1.  The character of the governmental action (invasive or regulatory);
        2.  The economic impact of the regulation on the claimant (Does 
            claimant still have any economic use of land available to it);
        3.  The extent to which the regulation has interfered with 
            reasonable ("distinct") investment-backed expectations.

Caveat: I am certain that some very central concepts have been omitted from this list, including the conflicting policy considerations (Central Operating Principles 1 through 4) which keep property law dynamic. Other essential concepts are hidden within a single word here and there. This structure may not mean anything to you. If that is the case, disregard it entirely and concentrate on those learning tools which work best for you.
