Actually, luckee, contempt covers a lot of areas. It just means you don\'t recognize the authority or position of the court.
Show up in tattered jeans and a ripped t-shirt, you could be cited for contempt.
Ignore a direct directive from a judge, contempt (don\'t ask that again, answer the question, etc).
Refuse the due process of law (refuse to swear - that\'s what the non-religious \'I swear that I\'m telling the truth\' one is for, refuse to co-operate with your lawyer, refuse to participate in jury pooling).
Just to further the choice point, when you work for the federal government in Canada, you have to give an oral oath of loyalty to Canada, under the ruling Queen Mother, and God. They do, however, have a non-religious version (which I took). It\'s really just a formality.
