On April 10, a group called No Somos Delito or We Are Not a Crime, projected a hologram of protesting marchers filing in front of the Parliament building in Madrid. For the time being, virtual protests in the form of holograms are not illegal in Spain. Incredibly, however, almost every other kind of peaceful protest soon will be if a new law goes into effect as scheduled on July 1.

The law on public security — dubbed the “ley mordaza” or “gag law” — would define public protest by actual persons in front of Parliament and other government buildings as a “disturbance of public safety” punishable by a fine of 30,000 euros. People who join in spontaneous protests near utilities, transportation hubs, nuclear power plants or similar facilities would risk a jaw-dropping fine of €600,000. The “unauthorized use” of images of law enforcement authorities or police — presumably aimed at photojournalists or ordinary citizens with cameras taking pictures of cops or soldiers — would also draw a €30,000 fine, making it hard to document abuses.

The law was introduced in 2013 by the government of Prime Minister Mariano Rajoy, whose conservative party enjoys a majority in both houses of Parliament. The lower house approved the law in December, and, despite pleas from rights groups and the United Nations, the Senate approved it last month.

The law’s main purpose, it appears, is to help the ruling party maintain its hold on power by discouraging the anti-austerity protests that have snowballed into widespread support for the populist Podemos party. Podemos looks set to make major gains in elections this year.
