The law offers several potential solutions applicable in a case. Determining which one is right implies discover which one is most reasonable. In this paper we analyze the origin of the reasonableness principle and the way it has been developed in the U.S. We also analyze how this principle has been enshrined in the Chilean Constitution, and how it has been applied by the jurisprudence of the Chilean Constitutional Court, to finally extract a list of reasonableness criteria emanating from this jurisprudence.
