[10] In September 2013, the news magazine Polityka commended Duda for being one of the most active members of parliament, describing him as being open to opposition arguments and as refraining from personal attacks, as part of his role at the Commission for Constitutional Responsibility.

[18] Duda rejected the European Union's proposal of migrant quotas to redistribute asylum seekers, saying: "I won't agree to a dictate of the strong.

I won't back a Europe where the economic advantage of the size of a population will be a reason to force solutions on other countries regardless of their national interests".

[19] In September 2015 Prime Minister Ewa Kopacz declared that Poland, as an expression of "European solidarity", would take in 2,000 people over the next two years, mainly from Syria and Eritrea (out of 3,700 originally requested).

[21] Duda repeatedly met with general secretary of the Chinese Communist Party, Xi Jinping,[22][23] stating that "Polish companies will benefit hugely" from China's Belt and Road Initiative.

[29] In 2024, Duda criticised plans by Prime Minister Donald Tusk to suspend the right to asylum in Poland by irregular migrants, calling it a "fatal mistake" that would also affect dissidents from Russia and Belarus.

[30] In November 2015, on the basis of Article 139 of the Constitution of Poland, Duda pardoned former Central Anticorruption Bureau (CBA) head Mariusz Kamiński and three CBA officers convicted by a court of 1st instance in the so-called "Land Affair" [pl],[31] marking the first pardon granted by a president before reaching a final verdict.

[33][34][35] Andrzej Duda refused to swear in any of the five Constitutional Tribunal judge candidates selected by the Sejm of the VII term.

[41] In July 2017, Duda informed the public he had decided to veto two controversial judicial bills backed by the government and passed by both houses of the Polish parliament.

[43] In February 2018, Duda said that he would sign into law the Amendment to the Act on the Institute of National Remembrance, making it illegal to accuse 'the Polish nation' of complicity in the Holocaust and other Nazi German atrocities, a measure that has roiled relations with Israel, with Prime Minister Benjamin Netanyahu going as far as accusing the Polish government of "Holocaust denial".

[47] He awarded it in recognition of Mosberg's achievements in advancing Polish-Jewish dialogue and developing cooperation between nations, and for preserving the memory of and communicating what happened in the Holocaust.

[47] In June 2020, Duda said that he would not allow gay couples to marry or adopt children, while describing the LGBT movement as "a foreign ideology" and comparing it to indoctrination in the Soviet Union.

[48][49][50][51] In response to Duda's comments, former Prime Minister of Belgium Elio Di Rupo publicly asked the European Commission for an official reaction.

[66] On 24 June 2020, Trump said at a press conference with Duda that the United States planned to move some U.S. troops from Germany to Poland.

"[69] In February 2022, Duda attended the opening ceremony of the Olympic Winter Games in Beijing and met with Chinese President Xi Jinping.

[73] On 9 January 2025, Duda asked Prime Minister Donald Tusk and his government to guarantee safe passage for Israeli Prime Minister Benjamin Netanyahu to travel to an event marking the 80th anniversary of the liberation of the Auschwitz concentration camp by Soviet troops, despite Netanyahu facing an arrest warrant from the International Criminal Court for Israeli war crimes in the Gaza war.

[75] On 29 May 2023, during a press conference, Duda announced the intention to sign the "Lex Tusk", a law establishing a commission to investigate Russian influence in Poland.

The Senate recommended the rejection of the law in its entirety due to its anti-democratic nature, numerous errors, and 13 potential violations of the constitution.

He took part in religious ceremonies on many occasions, including Midnight Mass, the blessing of food on Holy Saturday, and the Corpus Christi procession in Kraków.
