Legal Question in Admiralty Law in Louisiana

Possibly. Their failure to timely inform him of the positive drug test has certainly prejudiced him, as he can no longer get an independent test to prove that he did not have any drugs in his system. Personally, I would still go get an independent hair analysis done now. Hair tests go back much further than urine test (several months, rather than several days/weeks). While this will not show that he was drug free on the date of the last test, it will show that he has been drug free for several months and that he obviously does not have a drug problem.
