Which authority divides Himachal Pradesh into civil districts by notification in the Official Gazette under the Himachal Pradesh Courts Act, 1976?

Section 4(1) of the Himachal Pradesh Courts Act, 1976 empowers the State Government to divide the State into civil districts by notification in the Official Gazette, and the same provision lets it alter their limits and number. The High Court supervises and controls the subordinate civil courts but does not draw district boundaries. Neither the Supreme Court nor the Central Government has any role under this provision.
