Under the new constitution, the elections for Ethiopia's first popularly-chosen national parliament and regional legislatures were held in May 1995. Most opposition parties chose to boycott these elections as they did in 2000, in both cases giving the EPRDF a landslide victory. Opposition parties as a whole did finally participate in the 2005 election and the election produced a record number of voters, with 90% of the electorate turning out to cast their vote. The African Union report on the process commended the election for a "display of genuine commitment to democratic ideals ; the US Carter Center concluded that the majority of the constituency results were credible and reflected competitive conditions; the US Department of State said the elections stood out as a milestone in creating a new, more competitive multi-party political system. The EU Observer Mission, however, uncritically accepting some opposition claims, suggested the election had fallen short of international standards, though it actually classified nearly ninety percent of the polling processes as good or very good. The final results showed opposition parties had increased their seats in Parliament from 12 to an impressive 176, and that they had won all but one of the seats for the Addis Ababa City Council. Despite this, the main opposition coalition refused to accept the results, claiming against all the evidence that it had won. It called for a boycott of parliament, and organized a series of street protests in Addis Ababa at the beginning of November. These rapidly turned violent, and nearly 200 people including 7 policemen died in three days of rioting. A subsequent judicial commission of enquiry deplored the deaths but cleared the police of using unnecessary force. Thousands of people were temporarily detained. A number of opposition political leaders were convicted of various offences and jailed, but pardoned two years later.
Before the next election, in 2010, most of the parties, determined to avoid another outbreak of violence, signed an Election Code of Conduct. The exception was the largest opposition coalition, the Forum for Democratic Dialogue (MEDREK), a coalition of eight parties which included most of the groups that boycotted Parliament in 2005. When it came to the vote, the electorate proved unimpressed by the opposition refusal to take up its seats in 2005, and equally disenchanted by MEDREK's failure to sign the Code of Conduct, by the opposition's lack of alternative policies, its failure to do more than criticize the EPRDF and the public bickering and quarrelling among its leaders prior to 2010. In sharp contrast, after 2005 the EPRDF had revitalized its structures, building up extensive Women's and Youth organizations and reorganizing itself through the country. It won an overwhelming majority in local elections in 2008 and used this as a springboard for the national and federal elections in 2010. By then it also had the added advantage of presiding over significant growth and development, in infrastructure, primary education and health, and of achieving double-digit growth for the whole period between 2005 and 2010. It was hardly surprising that the results were a landslide victory for the EPRDF, including a total reversal of the Addis Ababa results of 2005 - in 2010 it was the opposition which only won a single seat, although over 40% of the city did vote for opposition parties. Elsewhere the EPRDF also achieved an almost clean sweep, with only one seat going to an independent. Overall, it won 499 of the 547 available parliamentary seats, and allied parties took another 46 seats. The opposition did just as badly in the regional state elections, with the EPRDF and parties allied to it winning all but one of the seats.
