JACKSON (WCBI) – The Mississippi Supreme Court says the owners of a Choctaw County power plant must honor a jury’s award of over $599,000 in tax payments. NRG Energy sued Choctaw County claiming the tax offices were using the wrong formula to determine the taxes. The county countered it was using the only formula authorized by the legislature. NRG says the company should have been granted a change of venue in the civil trial because the county leaders were all well known by jury members. NRG also argues an accounting principle it presented at trial was improperly excluded from jury deliberations. Entergy is in the process of purchasing the plant from NRG but a spokesman says the judgement is the responsibility of NRG and should not impact the proposed sale.
