Adoption of intertemporal problems of transmission easement is justified in relation to a large social importance of the new institution and especially due to the fact that the Act Amending the Civil Code did not contain any transitional provisions. Research has shown that the transmission easement may be established only from the date 3 August 2008 (date of entry into force of the amendment of the Civil Code). The adoption of a different view would remain in contradiction with the principle of lex retro non agit. However, when calculating the period leading to the prescription of transmission easement it is justified tu sum up the period of holding transmission easement from 3 August 2008 and a period of holding real easement in correspondence to the transmission easement before that date. This should justify the principle of direct effect of the new Act. On the other hand, when the term leading to easement prescription ended before 3 August 2008, there is the opportunity to acquire real easement corresponding to the content of the transmission easement.
