RCPI fielded three candidates in the 1982 West Bengal Legislative Assembly election; Mukherjee in Santipur, Kumar in Howrah Central and Mal in Hansan. In total the three candidates obtained 106,973 votes (0.48% of the statewide vote). Mukherjee and Mal retained their seats. Kumar lost the Howrah Central seat to Congress(I) candidate Ambica Banerjee. Kumar finished in second place with 29,785 votes (43.34%). After having lost his assembly seat, Kumar lost his post as minister. Bimalananda Mukherjee replaced him as the RCPI representative in the Left Front government. However, whilst Kumar had been a cabinet minister Mukherjee was named Minister of State (for Excise). In 1984 CPI(M) wanted to nominate Kumar for a Rajya Sabha (Upper House of the Parliament of India) seat, but that proposal met resistance from other Left Front partners. Kumar died in 1984.
