Dermody pushed an Indiana Retail Council-backed measure this year that would've sped up when Amazon.com would start collecting the state's 7 percent sales tax for online sales. That provision passed the House, but failed in the Senate.
Lifting the ban could continue to face a roadblock in the Senate, where Sen. Ron Alting, R-Lafayette, has also declined to take action on the proposal in the Public Policy Committee he leads.
Patrick Tamm, president of the Indiana Association of Beverage Retailers, which represents liquor stores, said he's not worried about Dermody's appointment.
New committee chairmen "always take a fresh perspective on things," but that doesn't necessarily mean anything is going to change, he said.
Sen. Phil Boots, R-Crawfordsville, expects to introduce a Senate bill lifting the Sunday sales ban. Boots said Dermody's appointment was a boost.
"I haven't had any discussions with him, but I think he's potentially more receptive than the previous chairman," Boots said. "... I'm optimistic, but I'm not confident. I'm hopeful."
