After the de facto merger on 1 November 1954 and before the legal integration with the Indian Union on 16 August 1962, general elections were held in 1955 and 1959.

the first general elections to the Pondicherry Representative Assembly (French: Assemblée représentative de Pondichéry) along with 16 municipal councils were held in 1955 from 18 to 23 July for 39 constituencies to constitute First Pondicherry Representative Assembly (French: Première Assemblée représentative de Pondichéry).

All the 8 seats in Pondicherry that were won by Congress came from the liberated areas of Nettapakkam, Mannadipet (Tiroubouvané) and Bahour communes.

On 9 August 1955 Then chief commissioner of Pondicherry, Mr. Kewal Singh also informed the leaders of the both Congress and People's Frony parties that unlike his predecessors during French rule, he would refrain from using his powers to nominate half of the six-membered Government-in-council (equivalent to council of ministries in Indian state assemblies).

On 12 August 1955, chief commissioner then invited the Congress led by Maurice Pakkirisami Pillai for the formation of government.

Initially, Maurice Pakkiriswamy Pillai led the Pondicherry Representative Assembly from 17 August 1955[9] until his death in January 1956.
