A bill allowing the use of public money to help the Carolina Panthers renovate their stadium could face a House vote Wednesday after winning approval from a key panel. But is it enough to tie the Panthers to Charlotte? The House Finance Committee passed the bill 21-11, but only after an hourlong debate that saw unusual alliances on both sides and could foreshadow arguments when the measure reaches the full House. The bipartisan bill would allow the city of Charlotte to use up to $110 million in local taxes earmarked for the Charlotte Convention Center to help upgrade Bank of America Stadium. But it’s a compromise that falls short of the Panthers’ initial request. The team had asked the city for $144 million and the state for $62.5 million toward a stadium upgrade of nearly $300 million. The city would have come up with its share by doubling the prepared food tax, which would require legislative approval. That deal came with a so-called tether that would keep the team in Charlotte for 15 years. But the compromise, if passed, would send the city and the team back to the negotiating table. “We need to let the bill progress through the legislature before we continue discussions with the city,” Panthers President Danny Morrison said in a statement Tuesday. Deputy City Manager Ron Kimble, who led negotiations with the team, said he’s not sure how the compromise bill would affect the tether. “Freeing up those (Convention Center) dollars doesn’t give us all of the funding in the current partnership with the Panthers,” he said. “But we appreciate all efforts … to keep the Panthers in Charlotte and North Carolina.”
