Mr Singh said after submitting resignations, Congress will go to people seeking their vote and support.
Punjab Congress Chief Amarinder Singh today said Congress MLAs in Punjab will resign en mass in case the Supreme Court verdict in the Sutlej-Yamuna Link (SYL) canal case goes against the state.
"While we respect the Supreme Court, we are also duty bound towards Punjab, hence we will find legislative and constitutional ways to safeguard our water which includes mass resignation by our MLAs", Mr Singh told a press conference in Jalandhar.
The PCC president said, after submitting their resignation along with his from the parliament, Congress party will go to people seeking their vote and support.
In case the verdict goes against Punjab and it orders construction of the SYL, Punjab will be left with no option.
Not only will over ten lakh acres of Malwa region go dry, people wouldn't even have water to drink, he said.
Amarinder said this will only be because of Chief Minister Parkash Singh Badal's failure to act on time.
"Either his (Badal's) intentions were not honest or they were not clear, which made him vacillate and waste crucial time in getting the Governor's assent to the unanimous resolution of the Vidhan Sabha on SYL, thus providing enough time to Haryana to move the SC," he observed.
There are always constitutional and legal means which must be exercised which Badal unfortunately squandered, he added.
Jalandhar MP Chaudhary Santokh Singh said he will also resign with Amarinder and the party legislators.
The PCC president warned Badal against any "mischief" that could imperil peace the state.
