Question: The governing bodies in each country operate league systems in a domestic season, normally comprising several divisions, in which the teams gain points throughout the season depending on results. Teams are placed into tables, placing them in order according to points accrued. Most commonly, each team plays every other team in its league at home and away in each season, in a round-robin tournament. At the end of a season, the top team is declared the champion. The top few teams may be promoted to a higher division, and one or more of the teams finishing at the bottom are relegated to a lower division.

Question: The city's first bus rapid transit line, the Metrobus, began operation in June 2005, along Avenida Insurgentes. Line 2 opened in December 2008, serving Eje 4 Sur, line 3 opened in February 2011, serving Eje 1 Poniente, and line 4 opened in April 2012 connecting the airport with San Lazaro and Buenavista Station at Insurgentes. As the microbuses were removed from its route, it was hoped that the Metrobus could reduce pollution and decrease transit time for passengers. In June 2013, Mexico City's mayor announced two more lines to come: Line 5 serving Eje 3 Oriente and Line 6 serving Eje 5 Norte. As of June 2013, 367 Metrobus buses transported 850,000 passengers daily.

Question: Greece was accused of trying to cover up the extent of its massive budget deficit in the wake of the global financial crisis. The allegation was prompted by the massive revision of the 2009 budget deficit forecast by the new PASOK government elected in October 2009, from "68%" (estimated by the previous New Democracy government) to 12.7% (later revised to 15.7%). However, the accuracy of the revised figures has also been questioned, and in February 2012 the Hellenic Parliament voted in favor of an official investigation following accusations by a former member of the Hellenic Statistical Authority that the deficit had been artificially inflated in order to justify harsher austerity measures.
Is there an answer to this question: When did the Parliament vote in favor of an investigation?

Answer:
February 2012
