Answer:
The correct answer is: Initially, yes it did violated the law. But it depends.
Step-by-step explanation:
To begin with, we need to understand that when it comes to the law of copyright the consequences of violating it depends on the particulary situation that the parties shared. Therefore that initially, Sesame Street would have violated the copyright law if they did not establish a contract that can allow them to use that story. However again, if in a first place the Reyher violated the law then Sesame Street will be out of charges becuase the first violation was caused by the writter and in other case it could also be seen as therewas no violation due to the fact that is a russian folktale and those stories have no copyright.
