If Mr Brunson is not released tomorrow and is instead convicted on charges of espionage - carrying a sentence of up to 35 years - or if the hearing is rescheduled, economic pressure could be ramped up against Ankara.
The United States has repeatedly called for his release. Saudi officials reject the claims as "baseless".
The fourth hearing against Andrew Brunson began at 10:40 a.m.in a prison complex in the Aliağa district of the coastal city of İzmir, ending at 4:28 p.m. with the court's ruling.

NBC's sources said an agreement on Brunson's release was advanced in discussions last month between Turkish and US officials, including Secretary of State Mike Pompeo and national security adviser John Bolton, during the United Nations General Assembly in NY.
The source cautioned that USA officials are counting on Turkish officials to follow through on their end of the agreement, which appears to now be in place with Brunson due to appear before a Turkish court on Friday. The Turkish government, however, have refused to budge on the matter.
