The Ulster Unionist Party has tabled a proposal at Stormont calling for the Union Flag to be flown every day of the year at Belfast City Hall.
Environment spokesman Tom Elliott said it was about equality and challenged other parties to back the measure in the draft Local Government Bill.
Weeks of loyalist rioting ensued after Belfast City Council voted to restrict the flying of the emblem from the City Hall in December 2012.
Mr Elliott said: “These are pragmatic proposals which I hope will be accepted and adopted by the Assembly this week. They are no threat to anyone’s identity.”
Dozens of police officers were injured after loyalist demonstrations erupted following the city council decision.
It meant the flag could only be flown on designated days like royal birthdays.
Mr Elliott added: “The Ulster Unionist Party amendment to the Local Government Bill calling for the flying of the Union Flag at City Hall for 365 days per year is an opportunity for some who claim that they are committed to equality to acknowledge what many of them signed up to when the Belfast Agreement came about.
“They should not deliberately confuse sovereignty with identity.”
