Burden of proof in tax court proceedings. In all proceedings before the judge or a magistrate of the tax court and upon appeal therefrom, a preponderance of the evidence shall suffice to sustain the burden of proof. The burden of proof shall fall upon the party seeking affirmative relief and the burden of going forward with the evidence shall shift as in other civil litigation. [1965 c.6 §5; 1995 c.650 §20]
