It is a principle of public trust (faith) = data entered in the Commercial Register are legally effective externally even if they do not correspond to the actual state, providing that conditions of the principle of publicity material (§ 27/2 of the Commercial Code) are applied.
positive side of the principle of publicity - records are legally enforceable against everyone (even the governmental agencies) from the date of publication of registration, but at the same time a person who knew about these facts previously, can apply them from the date of registration; the burden of proof of good faith of third people lies with the registered entrepreneur
declaratory entries - it is possible to actually apply from the time the third person hears them, but can not be relied upon prior to publication, or the end of the sixteenth day after publication (the enforceability of the special treatment given to the effectiveness of the registered facts - so if a certain fact is already effective because of the publication of the entry, but has not passed 16 days from publication of the entry and a third person proves that she could not know about it, it is not possible to enforced it against her)
constitutive entries - legal effects occur only at the time of publication, before the publication of the entry that effects cannot occur, but even here can not be relied upon up to the sixteenth day, if a third party proves that she could not know the facts. In other cases, the effectiveness starts from the date of disclosure
if there is a discrepancy between registered and published data or stored and disclosed documents, it is not possible to argue the published version against third parties, third parties may nevertheless rely on the published version, unless the registered person proves, that they were aware of the data entered in the Commercial Register or the contents of documents stored there
negative side of the material publicity - it is not possible to argue against a third party acting in reliance on a record that it does not reflect reality - the limits of the application of that principle is therefore trust of a third party - if such person knew or should have known about the differences between the registered data from reality, the actual situation is crutial compared to the Registry - this will be particularly the case where a third party will be the person to whom the record relates, specifically advised of the difference; burden of proof borne by the person whose registration is concerned, therefore, the written form of notice will be necessary in practice
