"as short a period as is practicable" (Art. 38(1))

Courts had the chance to specify how they interpret the period in which the goods have to be examined ("as short a period as is practicable", Art. 38(1) CISG). This period should be distinguished from the period in which the buyer has to notify the seller of the non-conformity under Art. 39(1) CISG, see here.
