Landlords representing more than 100 properties have submitted objections to a £100,000 alleygating scheme planned for South Belfast's Holylands area.
The city council plans to install 25 alleygates in the mainly student area at locations between Agincourt Avenue and Dudley Street in the latest phase of the scheme.
Residents and councillors have expressed support for the plans, saying that more alleygates will help tackle anti-social behaviour and fly-tipping.
