officer of the court

In the United States, the generic term officer of the court (not to be confused with court officers) is applied to all those who, in some degree in function of their professional or similar qualifications, have a legal part—and hence legal and deontological obligations—in the complex functioning of the judicial system as a whole, in order to forge justice out of the application of the law and the simultaneous pursuit of the legitimate interests of all parties and the general good of society.
