Ah. Now we’re seeing prosecutors in other countries dropping cases rather than reveal surveillance methods. RTÉ reports:
The prosecution case against three relatives of a prominent dissident republican collapsed in a Belfast Court today after a controversy about tracking devices used to gather information.
[…]
In a statement issued afterwards the Public Prosecution Service said that its case relied on evidence obtained from tracking devices that had been installed in vehicles.
It made a case to the judge that certain information about the devices should not be shared with the defendants but could be shared with an expert engaged by the defence team under a confidentiality agreement.
However, Mr Justice Colton decided that while accepting prosecution submissions about the sensitivity of the information, a fair trial required disclosure to the defendants.
The prosecution was not prepared to make known this information about the tracking devices.
Without this key element, the case collapsed.
