The ministers, while addressing press conferences in different parts of the country, also put the blame on Congress for the delay in getting this key reform bill passed.
Union Minister of State for Power Piyush Goyal said the government will work out alternatives to implement the GST and accused the Congress of "insulting the people of the country" by disrupting the legislative business in the just-concluded Parliament session where GST bill was stalled.
"We will hope that the Congress will realise the futility of stalling reforms like GST and will come on board," he said, but refrained from spelling out the 'alternatives' and said Finance Minister Arun Jaitley will "think over it and come out with an alternative at an appropriate time".
He ruled out Ordinance route for GST, saying constitutional amendments cannot be implemented by Ordinances.
Commerce and industry minister Nirmala Sitharaman said she is 'very optimistic' about getting the GST and other key bills passed in Parliament despite Congress' disruptions.
The government would seek to work with other parties in this regard, she told reporters in Chennai.
Union Environment and Forest Minister Prakash Javadekar told reporters in Lucknow that the GST Bill will "definitely" be passed and claimed the government enjoys "majority" in Rajya Sabha as well on getting this bill passed.
