The "right of competition" brought by trade liberalism today is not an unlimited right. The boundaries of this right are arranged by various laws. One of these related legislations is Turkish Commercial Code in which the article 54/2 defines unfair competition as "deceptive or other type behaviors and commercial practices in violation of the rule of integrity, affecting relationships between competitors or between suppliers and clients are unfair and unlawful". Article 55 of TCC mentions major examples of unfair competition cases. One of the mentioned unfair competition cases is "illegal disclosure of production and business secrets".In Article 55/I,d of TCC, with the provision "illegal disclosing of production and business secrets, especially by those who get benefit from or who inform third parties the information and production secrets that have been achieved in secretly and unauthorized way, is considered as dishonest action", a special unfair competition case like disclosing production and business secrets has been taken under regulation and an example is given to the unfair competition. Any technical and administrative information which is important and considered necessary for management would be interpreted as secret. This information is achieved as result of major investments and R&D works. Therefore, the principle of protecting labor which is the target of unfair competition regulations, is damaged by the unlawful disclosing of production and business secrets. "Disclosure of production and business secrets" will be evaluated in a comparable way with oTCC, TCC and related Swiss code with the perspective of the competitiveness should be based on one's own labor and effort principle.
