Manouchehrian was both Iran's first female lawyer and Iran's first female Senator. During her time as a Senator she was crucial in extending women's rights. Using her experience as a lawyer, she drew up the Family Protection Act, which granted women family rights. A number of elements in the proposed Act were picked out and greatly exaggerated by critics. This led to the Act becoming subject to great public debate and discussion in the media. Some members of the country's clergy claimed that the Act was not compatible with Islam, espoused loose moral standards and even considered publicly denouncing Manouchehrian as a heretic. Fearing for her safety, Manouchehrian fled Tehran for some time. The Act was later repealed following the 1979 Islamic Revolution.
