Satisfaction of a judgment against either the promisee or the promisor discharges the corresponding duty of the other party to the same extent, subject to subrogation rights.
How does 'thereon' function in the Model Penal Code provision on regaining possession of land?+
It identifies the specific land from which the person was dispossessed, clarifying that merely setting foot on the same parcel does not restore possession.
