The High Court reserved judgement at the conclusion of the two-day hearing into Town’s claim that Suffolk Constabulary unlawfully charged them for policing costs in the roads surrounding their Portman Road stadium on match days between 2008 and 2013. The Blues are suing for more than £200,000.
Mr Justice Green is now considering the evidence and is expected to make his decision within the next couple of weeks.
Suffolk Constabulary argue that the policing of closed roads such as Portman Road and Sir Alf Ramsey Way is inseparably linked to that inside the stadium and is therefore the club’s responsibility.
On Wednesday, Nick De Marco, for Town, told the court that the club "has been and currently is being charged by the police for ordinary policing on the public highway".
He continued: "This is unlawful as the police may not charge for discharging their normal policing duties.”
In 2012 the High Court ruled that West Yorkshire Police had overcharged Leeds United for "special police services" between 2009 and 2012, the Whites having argued that policing the roads and car parks around Elland Road is not their responsibility.
As a result of that ruling, Town were amongst a number of clubs to take similar action to reclaim cash previously paid - plus interest - for policing around stadia on match days. The Blues were charged from £5,926 to £25,242 per fixture.
But Dijen Basu QC, for Suffolk Constabulary, said there is a difference between the situations at Town and Leeds with match days in and around Portman Road "very peaceful indeed".
"That is a key distinction between the present case and that of Leeds United, whose fans have a very bad reputation for disorder," he added.
Suffolk Constabulary has subsequently issued a counterclaim against Town for more than £96,000 in unpaid invoices.
