A DERRY man stopped and searched under anti-terrorism legislation more than 150 times has lost a new High Court challenge to the police actions.
Steven Ramsey claimed the powers were used to detain him in breach of his human rights.
A judge found that PSNI failures to record the grounds for searches were inconsistent with a code of practice.
But dismissing the challenge, Lord Justice Treacy held that evidence established there was a basis for each incident.
Mr Ramsey is a former member of the 32 County Sovereignty Movement. He has stated he does not belong to any illegal organisation or political party and has no convictions for paramilitary activity.
He claimed he was subjected to 35 searches in 2009, 37 in 2010, another 23 in 2011, 31 in 2012 and 30 more up to August 2013.
Notes from some indicated he was stopped due to "suspected dissident republican links" or "as a result of confidential briefings".
From Derry's Creggan area, he contested the power to detain him on the basis that it breached his privacy entitlements under the European Convention on Human Rights.
His challenge focused on seven incidents after a code of practice was introduced in 2013. It was contended that the stop and search power is not subject to adequate legal safeguards to prevent it being used arbitrarily.
Although the judge rejected Mr Ramsey's original challenge in 2014, the case was remitted to him on appeal for a fresh hearing.
Ruling on the judicial review application for a second time, Lord Justice Treacy said the PSNI had not recorded grounds for the stop and search.
Written submissions provided by the police set out the basis.
The court was told one senior officer stated: "Steven Ramsey is a know(n) dissident republican who currently associates with persons engaged in dissident terrorist activity."
