President of the European Parliament
On 14 July 2009, Buzek was elected President of the European Parliament with 555 votes of the 644 votes cast, the largest majority ever, becoming the first person from the former Eastern Bloc and the first former Prime Minister since Pierre Pflimlin to gain that position. He succeeded the German Christian Democrat MEP, Hans-Gert Pöttering. He pledged to make human rights and the promotion of the Eastern partnership two of his priorities during his term of office, which would last two and a half years, due to a political deal, Social Democrat MEP Martin Schulz who take over after that.
In his inaugural address in Strasbourg, Buzek stated that among the greatest challenges faced by the European parliament were the economic crisis, European solidarity, human rights, and reform within the Parliament itself. Buzek also stated he would be committed to reform of the European economy, tackling rising unemployment, energy security, and climate change, strengthening European solidarity and integration and promoting equal opportunities for women. However, Buzek noted that the Lisbon Treaty would be a prerequisite to any change "(so that the Union can be) well-organised and effective".
On 8 December 2009 Buzek was awarded by the Ministerpräsident of North Rhine-Westphalia, Dr. Jürgen Rüttgers, the annual "Staatspreis award". The prize was awarded in honor of his lifetime achievements and highlighted the European Parliament as a "motor of integration." Affirming his commitment to the Eastern Partnership and "those who do not have the possibility to participate in our European integration project", Buzek announced that the prize money would be donated to the European Humanities University (EHU), A Belarusian university in exile in Vilnius.
The Lisbon Treaty, which came into force on 1 December 2009 shortly after Buzek assumed office, brought a conclusion to nearly a decade of internal discussions and greatly boosted the democratic powers of the European Parliament. From very early on Buzek has been a vocal supporter of the treaty as part of a wider push for greater political integration in Europe. The rise in legislative powers under the treaty in fact represents almost a doubling in power. Since its introduction Parliament has equal rights with the Council of Ministers over 40 new fields within the "co-decision" procedure, such as agriculture, energy security, immigration, justice and home affairs, health and structural funds.
In late 2011 Buzek's presidency also endorsed the 'Sixpack' legislation on economic governance to tackle the growing Eurozone crisis. This was a follow-up on the earlier Stability and Growth Pact and the Euro Plus Pact intended as a means of optimising macroeconomic surveillance in Europe and avoiding crises in the eurozone in the future. Welcoming the parliament's adoption of the legislation on 28 October 2011, Buzek stated: "The adoption of the six-pack by the whole European Parliament is good news for the European Union. We have a new economic rule-book. We have developed a powerful and resistant armour against any future crises. With the adoption of the six-pack, the EU significantly strengthens its budget discipline and moves towards true economic governance. We can not turn the clock back, but the package will ensure that Member States budgets will be credible."
One of Buzek's major challenges as EP president was dealing with the allegations of corruption, illegal lobbying and mismanagement of public funds of which several members of the European Parliament have been accused in the wake of a cash-for-amendments scandal. On 7 July 2011, the Conference of Presidents approved the first-ever code of conduct for MEPs and it was officially endorsed by the parliament on 1 December 2011. The code sets out rules and principles that MEPs should follow in their dealings with outside parties in order to avoid conflicts of interest. "Increased powers of the European Parliament must be accompanied by an increased transparency and accountability on behalf of its members" Buzek has said of the code. According to the code, MEPs have to provide clear declarations of their paid activities outside parliament, as well as the salary they receive. They also have to declare all other activities which might constitute a conflict of interest. The code contains an explicit ban on MEPs receiving payments or other rewards in exchange for influencing parliamentary decisions. It also sets out clear rules on the acceptance of gifts and on the issue of former MEPs working as lobbyists.
