La. Code Evid. art. 513
Current with changes from the 2024 Legislative Session
A person has a privilege, which may be claimed by him or his agent or employee, to refuse to disclose, and to prevent another person from disclosing, a trade secret owned by him, if the allowance of the privilege will not tend to conceal fraud or otherwise work injustice. When disclosure is directed, the judge shall take such protective measure as the interests of the holder of the privilege and of the parties and the furtherance of justice may require.
