In the 1999 parliamentary election the Socialist Party and the opposition won exactly the same number of MPs (115). Guterres was reappointed to office and from January to July 2000 occupied the six-month rotating presidency of the European Council. His second term in government was not as successful, however. Internal party conflicts, an economic slowdown, and the Hintze Ribeiro Bridge disaster damaged his authority and popularity. Nevertheless, some long-lasting measures were taken during his second term: in October 2000, the Parliament approved the decriminalization of drug use (effective 1 July 2001) and in March 2001, same-sex civil unions were legalized.
