The Public Accounts Committee is taking legal advice on whether it can cooperate with the Garda Ombudsman's investigation into penalty points.
The committee has concerns as to whether it can hand over all of its files received from a number of Garda whistleblowers.
It is due to hold a private hearing with serving Garda sergeant Maurice McCabe this afternoon, over allegations of malpractice in the penalty points system.
Laois Offaly TD Sean Fleming, who is a member of the committee, told Midlands Radio News the committee had to respect Sgt McCabe's request to meet the PAC in private.
"He has requested to meet us in private session," he said.
"The door is still open as to whether there will be a public meeting…It's not up to the Public Accounts Committee to put someone out on national television unless they agree."
