The UK Saville Inquiry [advocacy website] investigating the civil rights march in Londonderry Northern Ireland on January 30, 1972 ("Bloody Sunday") in which 13 civilians were shot dead by British soldiers may be further delayed as the soldiers may take the tribunal to court. The soldiers have argued against the use of any standard below the criminal standard of proof because of the potential consequences facing them.
Lord Saville [Wikipedia backgrounder], the head of the inquiry, has indicated that the tribunal will not use a criminal standard of proof to find if a soldier shot anyone without justification because the tribunal is merely investigating the circumstances surrounding the deaths and issuing a report.
