The purpose of this case commentary is to analyse the judgment of the European Court of Justice of 2 April 2020 in case C-830/18. The case concerns a student attending a German school whose right to a free journey to school was refused because he lived with his mother in the territory of France. The federated state argued that it is only obliged to organize school transport for pupils residing in that particular state. The Court did not agree with the federated state and pointed to the problem of discrimination against frontier workers. In examining the case, the Court focused not only on the rights of a pupil attending a German school but also on the social privileges afforded to his mother as a frontier worker. The text uses the method of an analysis of the law in force as established by the legislator.

Celem komentowanego orzeczenia jest analiza wyroku Europejskiego Trybunału Sprawiedliwości w sprawie C-830/18 z dnia 2 kwietnia 2020 roku. Sprawa dotyczy odmówienia prawa do bezpłatnych przejazdów do szkoły uczniowi uczęszczającemu do szkoły niemieckiej, a zamieszkującemu wspólnie z matką na terytorium Francji. Kraj związkowy argumentował swoją decyzję tym, iż jest on zobowiązany jedynie do organizacji transportu szkolnego wyłącznie uczniom zamieszkującym ten konkretny kraj związkowy. Trybunał nie przychylił się do zdania kraju związkowego i wskazał na problem dyskryminacji pracowników przygranicznych. Trybunał, rozpatrując sprawę, skupił się nie tylko na prawach ucznia uczęszczającego do szkoły niemieckiej, lecz także na przywilejach socjalnych przysługującym jego matce jako pracownikowi przygranicznemu. W tekście zastosowano metodę dogmatyczno-prawną.

"In this paper I show that within expected utility large buying and selling price gap is possible and [R] paradox may be resolved if only initial wealth is allowed to be small. It implies giving up the doctrine of consequentialism which may be reduced to requiring initial wealth to be total lifetime wealth of the decision maker. Still, even when initial wealth is allowed to be small and interpreted narrowly as gambling wealth, classic preference reversal is not possible within expected utility. I show that only another kind of reversal which I call preference reversal B is possible within expected utility. Preference reversal B occurs when buying price for one lottery is higher than for another, but the latter lottery is chosen in a direct choice. I demonstrate that classic preference reversal is susceptible to arbitrage whereas preference reversal B is not which suggests that the latter reversal is more rational."

We optimise a postal delivery problem with time and capacity constraints imposed on vehicles and nodes of the logistic network. Time constraints relate to the duration of routes, whereas capacity constraints concern technical characteristics of vehicles and postal operation outlets. We consider a method which can be applied to a brownfield scenario, in which capacities of outlets can be relaxed and prospective hubs identified. As a solution, we apply a genetic algorithm and test its properties both in small case studies and in a simulated problem instance of a larger (i.e. comparable with real-world instances) size. We show that the genetic operators we employ are capable of switching between solutions based on direct origin-to-destination routes and solutions based on transfer connections, depending on what is more beneficial in a given problem instance. Moreover, the algorithm correctly identifies cases in which volumes should be shipped directly, and those in which it is optimal to use transfer connections within a single problem instance, if an instance in question requires such a selection for optimality. The algorithm is thus suitable for determining hubs and satellite locations. All considerations presented in this paper are motivated by real-life problem instances experienced by the Polish Post, the largest postal service provider in Poland, in its daily plans of delivering postal packages, letters and pallets.
