Wow, leave it to an Aussie bitcoiner to discover the American system of banker oppression ... carried out with Federal Reserve money.  I've been redeeming lawful money (public money) for years here in the US, and can confirm that 'deadlizard' is (mostly) correct.  US notes were discontinued but still in circulation.  Not a moot issue, trentzb, and very much on topic.  The judge says the Constitution is not applicable because he's enforcing a private agreement - you've endorsed private credit of the Federal Reserve backside of your paycheck.  You are contracting.  Make your demand for lawful money instead as written in Section 16 of the Federal Reserve Act (codified at 12 USC 411) and you'll then be NON-contracting, operating outside the federal districts overlaid on the States.  If true, you realize that bitcoin operates outside their system too.  Bitcoin receipts are not income under the Revenue Acts, unless of course you consent to consider them so.  That's where the propaganda, psychology & conditioning come into play.

I haven't paid federal income taxes since 2007; no issues. Here's a company that beat the IRS using lawful money: http://savingtosuitorsclub.net/showthread.php?681-Company-beats-IRS-penalties-with-Lawful-Money

PS. beware.  There's a quatloser site out there that's disinfo - specifically setup by attorneys to steer you away from this.
