See www.bovinetb.co.uk/forum_topic.php?thread_id=46&page=1 and www.bovinetb.co.uk/article.php?article_id=56 for information on the infamous Boxster case. This case has set a legal precedent and it means that any cattle owner who believes that the tests for bTB have not been undertaken properly can challenge through the courts.
The Judge did not accept Defra's expert's argument and came to the conclusion that a test not taken according to the rules is invalid. This sets a legal precedent. Any test not taken according to the rules can now be challenged....
Any farmer who has a problem with bTB tests that were not done according to protocol can scuttle off to court and use Boxster's precendent...Of course a farmer can have a sound legal challenge with a such a test. DEFRA were so desperate not to set a precedent..... instead they have created a dirty great big one.
