Judicial power rests with the Supreme Court and the lower courts, as established by law (Art. VIII, sec. 1 of the 1987 Constitution). Its duty is to settle actual controversies involving rights which are legally demandable and enforceable (Art. VIII Sec. 1 (2)).
The judiciary enjoys fiscal autonomy. Its appropriation may not be reduced by the Legislature below the appropriated amount the previous year (Art. VIII, sec. 2).
