The report states the unconstitutionality of article 38 ter of Law No 18.933 based on three main arguments. First, it would violate the legal reserve warrantee and principle of the fundamental rights; hence it makes the regulation of the ISAPRES plan's prices fall under the general guidelines passed by the Superintendence of ISAPRES. Secondly, the risks factor table -established in said article- violates the principle of equality by setting an unjustified differentiation conditional to sex and age. Finally, it affects the freedom of the subscriber to really choose the health system, since the ISAPRE could marginalize the users of the system when fixing prices, hence restricting the real freedom of the choosing.
