In 2009, President Tandja Mamadou decided to organize a constitutional referendum seeking to extend his presidency, which was opposed by other political parties, as well as being against the decision of the Constitutional Court which had ruled that the referendum would be unconstitutional. Mamadou then modified and adopted a new constitution by referendum, which was declared illegal by the Constitutional Court, prompting Mamadou to dissolve the Court and assume emergency powers. The opposition boycotted the referendum and the new constitution was adopted with 92.5% of voters and a 68% turnout, according to official results. The adoption of the new constitution created a Sixth Republic, with a presidential system, as well as the suspension of the 1999 Constitution and a three-year interim government with Tandja Mamadou as president. The events generated severe political and social unrest throughout the country.
