There was a man of the hill-country of Ephraim, whose name was Micah.
The reason why some critics (as Dalglish did, for example) attempt to date these last five chapters in "a period following the fall of the Northern Israel at a time after 734 B.C.,"[1] is obviously due to their efforts to avoid the positive proof of the existence of the Pentateuch at a time long PRIOR TO the Book of Judges, as dramatically indicated by the undeniable references to the Book of Moses abounding in these chapters.  Of course, the acceptance of these references as having existed when Judges was written effectively proves that the dating of the Pentateuch in the times of Josiah is nothing but a rather clumsy fairy tale.
