In the quadrennial marathon to see who can be the nation’s worst governor, Colorado’s Bill Ritter is in a full sprint. On Thursday, Ritter signed Senate Bill 200 which expands “anti-discrimination” law to cover sexual orientation, meaning not only homosexuality or bisexuality, but also “transgender status or another person’s perception thereof.”
The bill is so ripe for abuse and creates so much risk for private business that it’s no surprise the ordinarily media-hungry Ritter signed the bill late in the afternoon (too late for most newspapers to cover the story) with no fanfare (although he frequently has bill-signing ceremonies and particularly for measures such as this which have received this much media attention). It isn’t even mentioned on his Web site, whereas a look at the page shows that he routinely issues press releases on bills he signs into law.
A major criticism of the bill by conservatives is that it appears to allow men who self-identify as “transgender” a legal right to demand to be able to use women’s bathrooms, health club showers, bathhouses, and any other “public accommodation”.
Importantly, the bill does not define “transgender”. The Wikipedia entry on the term notes that “the precise definition for transgender remains in flux, but includes:
• A person whose identity does not conform unambiguously to conventional notions of male or female gender, but combines or moves between these.
• People who were assigned a gender, usually at birth and based on their genitals, but who feel that this is a false or incomplete description of themselves, and
• Non-identification with, or non-presentation as, the gender one was assigned at birth.”
In other words, not only is there no legal definition for transgender, but there isn’t even a solid dictionary definition for a court to rely on. Instead, transgender status is a matter of self-identification, rendering such a claim to be nearly impossible to prove or disprove.

Basically, if you just say you "identify with" the other sex you can just nip into whatever restroom you want to use.
