A bill proposed by the cabinet of the former Italian Prime Minister Mario Monti would have further lowered the protection level of Sardinian, distinguishing between the so-called "national minorities", speaking languages protected by international agreements (German, Slovenian, French) and the "linguistic minorities" whose language is not spoken in any state other than Italy (all the other ethno-linguistic groups, including Sardinian). This bill, which was eventually implemented but later deemed unconstitutional by the Court, triggered a reaction on the island. Students expressed an interest in taking all (or part) of their exit examinations in Sardinian. In response to a 2013 Italian initiative to remove bilingual signs on the island, a group of Sardinians began a virtual campaign on Google Maps to replace Italian place names with the original Sardinian names. After about one month, Google changed the place names back to Italian.
