Contempt, penal code section 166
This is a rather weird question... so I apologize ahead of time.
''Contempt of Court'' is sometimes charged as California Penal Code section ''166.4'' and sometimes as ''166(a)(4)'' (Not to mention to other sections in the Code of Civil Procedure...). How does ''166.4'' differ from ''166(a)(4)''? Is 166.4 a real section of the code (which I cannot find online), or is it some kind of shorthand? The official online version of the Penal Code (from leginfo.ca.gov) only lists 166 and 166.5 (twice?).
Any information I could get clearing this up would be great.
