Note that October 15 is the 75th anniversary of the execution by firing squad after a summary trial of Catalan President Lluís Companys by fascist rebel forces led by Francisco Franco. Whether the judges knew that when they chose the date is unknown, but that they chose not to change the appearance when it was found out, is a matter of public record.
The following is an on-the-fly translation of parts of Mas' declarations immediately following his testimony. It is neither exhaustive nor completely exact—though that is always my intention.
Herein lies the basic defense: Catalan govt passed law on non-binding referendums, and used it to sign decree on non-binding vote. Spanish govt suspended that law within 48 hours. President changed format to "participatory process" on October 14, and for the next 15 days, the Spanish goverment mearly scoffed. It was not until four or five days before the vote that the Spanish court suspended the participatory process as well. President says that all Catalan govt action took place before second suspension, and that anything that took place after the suspension was carried out by volunteers. His and VP's evaluatin of results falls into regular duties as president.
