This paper which is based on court orders of Ottoman Judiciary (between 17th and 18th centuries), aims to discuss that regulation almost has 300 years past in Turkey's economic history. It is realised that Ottoman courts' verdicts and today's regulation authority orders have some similarities though they had not given under similar circumstances. These similarities are described from past to present by the point of purpose and qualification of regulations. In this setting, judicial conception of Ottoman courts to regulate is considered in terms of today's regulation mentality.
