The MPA began its legal action against UK-operated Newzbin in 2010, which resulted in the High Court telling the site to remove material it hosted that infringed copyright.
Newzbin went into administration soon after but its assets, including web domains, were sold to new owners and a fresh version of the site has popped up operating out of the Seychelles.
"Newzbin has no regard for UK law and it is unacceptable that it continues to infringe copyright on a massive and commercial scale when it has been ordered to stop by the High Court," said Chris Marcich, European president of the MPA, in a statement.
"We have explored every route to get Newzbin to take down the infringing material and are left with no option but to challenge this in the courts."
Court-imposed blocks have been used widely throughout Europe but a success for the MPA would mark the first time the tactic has worked in the UK.
