The principle of dispositivity is developed based on the concept of party autonomy that is characteristic of civil law regulation that covers business activities and is realised through the application of, in addition to directly applicable imperative norms, dispositive norms that imply the freedom of the parties to perform (to acquire, realise and dispose of) their rights on their own discretion. Particularly in respect of the civil law relations the law provides the parties with large possibilities to determine their relations in accordance with their autonomy of will and in default of such determination offers the applicable rules. Essentially important in realisation of the principle of dispositivity in the civil law are also initiative norms through the application of which the civil law relations emerge, change and cease. Related particularly to the contract and corporate law regulation in Russia, the traditional totality of the legislative law has been challenged in the pragmatic approach supported by the Russian highest judicial body. According to the Ruling of the Plenum of the Supreme Arbitrazh Court of 2014, the norm that determines the rights and obligations of contractual parties but does not include the expressed provision of its dispositivity or imperativity, ought to be recognised as dispositive or imperative in accordance with the interpretation of its aims, and this indicates of favourable attitude towards business activities as well as of reasonable implementation of the pragmatic attitude that is characteristic to common law to Russian law. In particular, the favouring of the principle of dispositivity in respect to business law regulation, by the concentration of the valuation of the dispositivity of a legal norm in the sphere of successive control, instead of previous control, actually promotes the real freedom of business activities, and makes the regulation flexible. This is particularly important for small and family enterprises that are very common in Russia. Keywords: Dispositive Norm; Initiative Norm; Contract Law; Corporate Law; Pragmatic Approach
