for exposing their breasts while breastfeeding in public. A public backlash spurred legislators in some jurisdictions to specifically legalize public breastfeeding. The federal government passed a law in 1999 that specifically provides that "a woman may breastfeed her child at any location in a Federal building or on Federal property, if the woman and her child are otherwise authorized to be present at the location." Some women have engaged in acts of "lactivism", or acts of politically motivated public breastfeeding, to assert these rights. In many indigenous, non-Western cultures it is generally acceptable for both men and women to go without clothing that covers the torso. Female toplessness can also be a traditional aspect in indigenous cultural celebrations. However, this can lead to cross-cultural and legal conflict. During 2004, Australian police banned female members of the Papunya community from using a public park in the city of Alice Springs to practice a traditional Aboriginal dance while topless. Many societies consider women who expose their nipples and areolas as immodest and contrary to social norms. Most jurisdictions do not have laws prohibiting toplessness directly, but in many jurisdictions a topless woman may be socially or officially harassed or cited for public lewdness, indecent exposure, public indecency or disorderly conduct. Enforcement of such standards is subject to community standards, which are subject to change over time. Most prosecutions commence with a complaint being made to the police by a member of the public, and a judge would be required to adjudicate as to the indecency etc. of the exposure. In the United States, GoTopless.org claims that women have the same constitutional right to be bare chested in public places as men. They further claim constitutional equality between men and women on being topless in public. They have successfully joined in legal challenges that have resulted in laws permitting women to expose their breasts just as men do in New York State and in Ontario, Canada. In 2009, they used 26 August (Women's Equality Day), as a day of national protest. The topfreedom movement has claimed success in a few instances in persuading federal courts in the United States to overturn some state laws on the basis of sex discrimination, arguing that a woman should be free to expose her chest in any context in which a man can expose his. A federal lawsuit filed in the 10th Circuit (Colorado), was decided at
