In 2005, the German Federal Constitutional Court ruled that a federal law prohibiting tuition fees was unconstitutional, on the grounds that education is the sole responsibility of the states. Following this ruling, seven federal states introduced tuition fees of €500 per semester in 2006 and 2007. Due to massive student protests and a citizens' initiative which collected 70,000 signatures against tuition fees, the government of Hesse was the first to reverse course before the state election in 2008; other state governments soon followed. Several parties which spoke out for tuition fees lost state elections. Bavaria in 2013 and Lower Saxony in 2014 were the last states to abolish tuition fees.
