The chief minister's adviser, who was questioned by police in connection with the alleged assault on Prakash at Kejriwal's residence on February 19, proceeded on a week's medical leave after questioning by the Delhi police.
Addressing the media separately, Sisodia and Maken also attacked the Bharatiya Janata Party (BJP) for not taking part in the meeting, despite an invitation from Kejriwal.
"There are some issues on which we should not do party politics", he said.
Congress president Rahul Gandhi on Tuesday accused the BJP and the AAP of "collusion" on the ongoing "sealing drive" issue and asked both the parties to stop blaming each other and find an immediate solution to the problem.
"Stop the drama of allegations and counter-allegations on the issue of sealing in Delhi".
Addressing a press conference after the meeting held at the chief minister's residence in Delhi, Mr Sisodia said Mr Maken had assured them that Congress lawmakers would raise the sealing issue in Parliament along with Aam Aadmi Party lawmakers. "I assure you from my side that my party and government will do whatever is needed to put an end to sealing and to reopen shops that have already been sealed", wrote the Delhi Chief Minister. "The discussion for traders was necessary and if needed, we will again call a meeting and appeal to the BJP to attend it", Sisodia said.
The trading community is traditionally seen as a constituency of the BJP, and the attempt by the AAP is to portray the BJP-which rules the three municipal corporations that are carrying out the sealing drive on court orders, and which is in power at the Centre-as being responsible for the action, and hence as being "anti-trader".
Maken said he had suggested that the government effectively tackle the sealing case in the Supreme Court, and added that as the government had so far not approached the monitoring committee, an all party-delegation should meet the court panel to discuss the issue.
Sisodia said the BJP could resolve the issue "immediately" if it wanted to. The AAP criticised BJP chief Manoj Tiwari, who was overseas, for choosing to be in a foreign locale when traders in the city were suffering because of the sealing action.
The Confederation of All India Traders (CAIT) said that over seven lakh shops in 2,500 markets across the city were shut on Tuesday.
The sealing drive is being carried out on the order of the Supreme Court over "misuse of premises".
