Va. Judge Says Parts of DWI Laws Illegal

McLEAN, Va. -- A district judge has ruled that key components of Virginia's drunken driving laws are unconstitutional, citing a decades-old U.S. Supreme Court decision.

The state law presumes that someone with a blood alcohol content of 0.08 or higher is intoxicated, denying their right to a presumption of innocence, Judge Ian O'Flaherty ruled in dismissing charges against at least two alleged drunken drivers last month. . . .

[C]orinne Magee, a defense lawyer who first successfully argued the issue to O'Flaherty, said the ruling is based on a 1985 U.S. Supreme Court case that deals with prosecutors' obligation to prove all elements of a crime beyond a reasonable doubt.
