richterliche
"Richterliche" means "judicial" or "pertaining to a judge."
Here, 'richterliche' describes 'Gewalt', showing that this is the power associated with judges or courts within the context of state structure.
Die richterliche Gewalt ist eine der drei Gewalten in einem Staat.
The judicial power is one of the three powers in a state.
Here, 'richterliche' is used adjectively to describe 'Entscheidung', specifying that the decision is made by a judge or judicial authority.
Die richterliche Entscheidung hat den Fall geklärt.
The judicial decision resolved the case.
In this sentence, 'richterliche' again functions as an adjective modifying 'Anordnung', indicating the order originates from a judicial process.
