Abstract
Admissibility of formulating principal and alternative claims in civil proceedings is commonly accepted in the doctrine and in case law. Regrettably, the fact that there is no statutory regulation specifying the very notion of an alternative claim, the basis for its being adjudicated in the proceedings, as well as formal and fiscal requirements for making it gives rise to many practical problems. The author has made an attempt to propose their resolution in the proceedings before a court of first instance and in appellate proceedings.
