We have not been convinced, on-motion for rehearing, that our previous de
*229
cisión in this case was incorrect. However, it has been the pattern in this jurisdiction that in tax matters, when a previous decision is overruled, the new decision is given prospective effect only. See e. g. Duhame v. State Tax Commission,
Therefore, in fairness to the parties who have relied upon the previous holding of this court in Ashton Company v. City of Tucson,
A ruling which is purely prospective does not apply even to the parties before the court. Linkletter v. Walker,
We adhere to our decision in this case, with the exception that it shall not apply to transactions consummated prior to the date thereof.
For the reasons herein stated, the previous decision of this court is modified as to the disposition of the instant case and the judgment is affirmed.
KRUCKER, C. J., and HATHAWAY, J., concur.
NOTE: This cause was decided by the Judges of Division Two as authorized by A.R.S. § 12-120, subsec. E.
