Choice of law refers to the law of a given territory in accordance to which any legal dispute will be resolved. An example is the law chosen for court decision or commercial arbitration. When there is a legal dispute in the acts of developing or using free software programs, the legal relationship among the programmers or between the vendors and the package makers are often cross-border in nature. Although the legal code may mostly be the same in the territories involved, there are still nuances and differences. The first dispute will then be which territory’s law to be used. To avoid such dispute, some free software licenses specify the choice of law. You may refer to ‘Law Governing Foreign Civil Affairs’ for the details on the choice of law in Taiwan. This also belongs to the domain of’ Private international law’.
