The January 7, 1977 Supreme Court ruling in State of Washington v. Wanrow was an important victory for the feminist cause of gender-equality before the law. In a landmark ruling, the Washington Supreme Court, sitting en banc, declared that Yvonne Wanrow was entitled to have a jury consider her actions in the light of her "perceptions of the situation, including those perceptions which were the product of our nation's long and unfortunate history of sex discrimination." The ruling was the first in America recognizing the particular legal problems of women who defend themselves or their children from male attackers, and was again affirmed by the Washington Supreme Court in denying the prosecutor's petition for rehearing in 1979. Before the Wanrow decision, standard jury instructions asked what a "reasonably prudent man" would have done, even if the accused was a woman; the Wanrow decision set a precedent that when a woman is tried in a criminal trial the juries should ask "what a reasonably prudent woman similarly situated would have done."
