Italy on Tuesday lost a long battle to hold on to one of its most cherished and ancient family traditions: requiring children of married couples to take the father's surname only.
An Italian law excluding offspring from having the option to be registered under the mother's maiden name was "patriarchal", "discriminatory" and a rights violation, the European Court of Human Rights ruled, ordering it be ended.
The patronymic practice constituted a "difference of treatment between men and women," the Strasbourg-based court said in its judgement.
In doing so, it sided with an Italian couple who have fought for 13 years to have their children carry the wife's maiden name, rather than the husband's last name.
Alessandra Cusan and Luigi Fazzo had taken their case to the top European court after losing all their battles in Italy's courts to have their daughter born in 1999 named Maddalena Cusan instead of Maddalena Fazzo, as authorities required. They also wanted Cusan to be the surname of their two subsequent children.
The requirement they stick to the father's surname was an infringement of their private lives, they argued.
They won a half-victory at the end of 2012 by gaining permission from local authorities to add the mother's name to that of the father's for Maddalena, but that was not sufficient and they took the issue to the European rights court.
The Strasbourg tribunal did not order the Italian state to pay any damages, but declared that the impossibility to register Italian newborns under a married woman's last name was "excessively rigid" and discriminatory.
While recognising that Italy's legal tradition had its roots in a practice dating back to the ancient Roman era, the court said it was today incompatible with the Italian constitution's principle of gender equality.
Rome will now have to change its legislation to comply with the ruling, it ordered, unless it lodges an appeal with a higher chamber in the European court within three months.
Other European countries are more flexible in the choice of a baby's surname. In France, for instance, a child can carry the last name of the father or the mother, or a combination of both.
