Senior AAP leader Ashutosh mocked the decision saying it was "reflective" of Congress' "commitment" to fight against corruption.
AAP has been demanding action against Dikshit alleging her involvement in a number of irregularities during her tenure as Delhi Chief Minister.
Mishra said that Dikshit became "politically active" the day the Delhi Jal Board (DJB) fact-finding committee report in the alleged wanter tanker scam was sent to the LG-appointed Anti-Corruption Branch (ACB) chief MK Meena.
The ACB today sent a notice to Dikshit asking her to join the investigation in connection with the alleged Rs 400-crore water tanker scam on August 26. Dikshit called the allegation "politically motivated".
Mishra said it was merely a "delay tactic" on the probe agency's part. "Today or tomorrow, she will have to go to jail," he tweeted.
