A stipulation is an agreement and it becomes an order once approved and signed by the judge.  In the case of S&Os related to the appointment of Judge Ouderkirk, it has to be approved and the Order made by a regular Superior Court judge. 

The S&O on the appointment of Judge Ouderkirk, was first approved by the court in 01/09/2017.
