Legal watchdog Earthjustice filed suit today against the federal government over the new ozone standard, which was more lenient than government science advisers had advocated.

The lawsuit is no surprise. Congress asked a lot of questions last week to find out how the U.S. Environmental Protection Agency decided on setting the threshold -- a threshold that will take decades for the San Joaquin Valley to achieve.

One interesting sidelight: You can read the entire lawsuit in about 30 seconds.

Why? In Clean Air Act lawsuits like this one, the suit is filed with a simple statement directly in the circuit court of appeals, in this case it was in the District of Columbia. That's so anyone, including you, could easily protest such a big federal decision on air quality.

However, you can be sure that in the coming months, there will be a lot more detail about the case. If you're going to file this kind of a lawsuit, you're going to need a lawyer and a lot more than a single sentence.
