If you are applying for Italian Dual Citizenship through a "female" line, you may fall in the category of those born to an Italian female ancestor before 1948. The 1912 Citizenship Law granting Italian citizenship jure sanguinis stated that women could hold but not pass citizenship to their children. However, in 1948 when Italy became a Republic a new Constitution did allow for women to pass on citizenship but only to children born after January 1, 1948. The Italian Supreme Court recently held that this provision is contrary to the Constitutional principles, particularly to the principle of equality between men and women (Judgement No. 4466/2009). Thus, also children who are born before 1948 to an Italian mother, may file a motion to appeal the "1948 Rule" and obtain, if eligible, Italian citizenship.
Even though the Italian Supreme Court ruled against the 1948 Rule, the Italian government has not yet chosen to modify or amend the current law. US Italian Consulates and other Italian Consulates outside of Italy strictly adhere to the current 1948 Rule. Thus, the legal action to be filed at the Court House in Rome is your only way to obtain citizenship. More here (https://www.myitalianfamily.com/resource-center/challenging-1948-rule-italy)
