Pursuant to the students are allowed to photocopy or reproduce the whole or part of copyrighted materials for the purposes of research and study which is not for profit, as long as such reproduction does not conflict with a normal exploitation of the copyright work are is not unreasonably prejudicial to the legitimate right of the copyright owner. The difficulty lies in determining the permitted amount of reproduction. Similarly, the exception concerning teaching and education institutions does not have a clear limitation as to the quantity allowed to be reproduced and does not prohibit multiple reproductions of copyrighted materials. No judicial decision by the Thai Court on this matter. The Court implied that there is an issue relating to the duplicate quantity in Thailand, due to the difficulty in determining the justifiable quantity of reproduction under the exception for research and study. In practice, the interpretation of these phrases seems to be difficult for both users and Thai court to determine on a case-by-case basis. With such an unclear provision, it is extremely hard for users or even government officers to know how much of a copyright work can be legally reproduced for research and study.
