After the end of his government, in November 1954, Pella was elected President of the Common Assembly, the plenary assembly of European Coal and Steel Community (ECSC), which had been considered as the prototype of the European Parliament.
He hold the office until November 1956.
His pro-European vision was clearly outlined already in the inauguration speech as president, where he sustained the need to create a Europe "inspired by the concept of supernationality, built not against nations but with the sincere collaboration of nations."
Few years later, discussing about his years at the head of the European institution, he stated that he always held his office "with the determination to pursue the strategic plan of a progressive transfer of sovereignty from the member States to the European institutions."

In 1954, he founded, along with Giulio Andreotti, a right-wing faction of Christian Democracy, known as "Concentration".
In 1955 he was one of the kingmakers of Giovanni Gronchi's election to the Presidency of the Republic, against Cesare Merzagora, who was the candidate proposed by the Christian Democratic secretary, Amintore Fanfani.
Pella and Andreotti's move gained the surprising support of communist and socialist parties, as well as the one monarchist and neo-fascist movements.
After Gronchi's sworn in, Pella was considered the natural candidate for the premiership, however the new President of the Republic appointed Antonio Segni.

In May 1957, Pella served as Minister of Foreign Affairs in the government of Adone Zoli, of whom he served also as Deputy Prime Minister.
He became Foreign Affairs Minister again under Segni, from February 1959 until March 1960, and Minister of Budget in Fanfani III Cabinet from July 1960 to February 1962.

A strong opponent of Fanfani's alliance with the Socialist Party, from 1962 he decided to keep aside.
In the later years, he became president of the Senate Foreign Affairs Committee from 18 July 1968 to 23 February 1972 and briefly returned to the government as Finance Minister in the first government of Giulio Andreotti from February to June 1972, which however failed to gain confidence by the Parliament.

After leaving politics in 1976, he continued his role of President of "National Association of Insurance Institutes" and of the "Association of Tax Advisors and Accountants".
He also led "Piemonte Italia", a promotional institute of studies on the regional economy, which he founded in the 1960s.

Pella died on 31 May 1981 in Rome, at the age of 79.
