Charges Against Ponsati

On October 1, Catalonia held an independence referendum, which the central authorities did not recognize. The results showed that the majority of Catalans supported secession, and the regional parliament unilaterally announced independence later in October. In response, Madrid imposed direct rule over the autonomous region, dissolved the Catalan parliament and called a snap election. Several pro-independence leaders were jailed, while others fled to Belgium.

Following the independence vote, Ponsati fled to Belgium with former Catalan leader Carles Puigdemont and three other regional politicians. In March, Ponsati moved back to Scotland and her position as a professor at St. Andrews University.

On Friday, the Spanish Supreme Court activated a European arrest warrant for a number of Catalan politicians, including Puigdemont and Ponsati. Shortly after, Puigdemont was detained in Germany after he crossed the border with Denmark on his way from Finland to Belgium.

According to the Spanish Prosecutor's Office, Ponsati was responsible for allowing polling places to stay open in schools during the referendum. She is charged with organizing an insurrection — which under Spanish law can mean a prison sentence of up to 30 years — as well as embezzlement of state funds.
