Indeed it does, and it's probably better explained using a triple point diagram:

On earth (at higher pressures), increasing temperature goes from the solid, to liquid, and then to gas phases (the triple-point in the middle is at zero degress celcius)

The lower atmospheric pressure on Mars (~1% of sea-level earth pressure) means that you go straight from solid to gas. In fact, the liquid part is actually impossible (IANAChemist) unless you increase the pressure sufficiently.

I have created a page to inform and organize a resistance against this law. If we collect 50'000 signatures until the 24th of January however, we can force a national vote on this law. Help me in any way that you can fight this law. I was first made aware of this two days ago by this article on slashdot."
