All the cases that were registered last year during Kejriwal government's 49-day stint "will be pursued", he said.
Sisodia, who had been asked whether the FIRs lodged by the AAP government last year against Mukesh Ambani, the then Petroleum Minister M Veerappa Moily as also allegations against Dikshit would be pursued, responded "yes, definitely".
The then Chief Minister Arvind Kejriwal had ordered filing of an FIR on February 11 last year against Moily, his predecessor Murli Deora, who is dead now, and RIL Chief Mukesh Ambani for alleged collusion in hike of prices in natural gas from the KG basin.
The then AAP government had also ordered a probe into street light purchase scam during the Commonwealth Games of 2010 in which Dikshit's role had come under the scanner.
Sisodia said the AAP government will "revive" the cases that have been put in cold storage and take them to a "logical conclusion".
On its key poll promise of slashing power tariff by 50 per cent, Sisodia said it would be done "as soon as possible".
Alleging wide-spread corruption in the power sector, Sisodia said the new government would force the power distribution companies to give all their financial details to the CAG that is probing their accounts.
The CAG audit into the finances of the private power distribution companies was ordered by the Kejriwal government last year.
In its manifesto, AAP had promised to cut power tariff by 50 percent immediately after coming to power and said the rates will be revised based on the findings of the CAG audit.
"CAG audit into the discoms is already going on. We will force them to give all the details to the CAG," Sisodia said.
