Samuel Newey was charged alongside two other men, accused of assisting his relative to prepare for acts of terrorism.
Mr Singh had applied to dismiss the charges and argued that bringing the prosecution was an abuse of process.
The Prosecution made the decision to drop the charges, providing the only explanation that there was no longer a realistic prospect of conviction. The decision followed a number of defence requests for the disclosure of more information held by the Prosecution.
