Do you realise that UKIP were about the only party that voted against the EU parliament's call to have the details of the ACTA negotiations made public?
Their statement if this is the correct vote you are referring to:
"Whilst we as a group voted against the ACTA Resolution on Wednesday 10th March 2010, we did so on the principle that the ACTA Treaty itself should not exist in any form. It is a catastrophic violation of individual private property. Had we voted to support the Resolution, we would be recognising the existence of such legislation and on that basis we decided not to recognise the Treaty."
