The Indiana Supreme Court will hear an appeal involving a lawsuit seeking a lawmaker's emails and other correspondence with utility company officials over solar power legislation he sponsored.

The Citizens Action Coalition, Common Cause Indiana and the Washington D.C.-based Energy and Policy Institute filed a lawsuit in May under the Access to Public Records Act, or APRA, after the House GOP caucus denied them access to emails between Bedford Rep. Eric Koch and several utility companies.

The Indiana House Republican Caucus is facing a lawsuit over its decision to withhold emails shared between one of its members and several utility companies.
