Lawyer for the trustees Tio Faulkner presented his case saying the council never had lawful authority to name this stretch of land a road.
Mr Faulkner also debunked the Public Works Act 1883, which dealt with land taken for the purpose of a road, as it never applied to this "pathway" used by Maori.
But the real reason behind the delay of judgement was because of the colouring on the most recent maps of the land area.
The colour, known as "burnt sienna", was used as an indicator to show where roads were on land maps.
Tauranga City Council lawyer Nicky Hall brought in former Land Information New Zealand worker John Neil to give his expert opinion as to whether burnt sienna was present on the strip of land in question.
It sounded like a trivial matter, but Justice Whata told Mr Neal he saw no colour other than white, whereas Mr Neal said he saw a "pale" colour that he believed was burnt sienna, indicating it was indeed titled as a road, meaning the council had authority to build on top of Crown land.
As Justice of the court, Mr Whata said he had the right to dispute the information given by an expert witness if he didn't think it was accurate.
While not going so far as to dispute the evidence, enough doubt was expressed, resulting in Justice Whata asking for an independent expert to examine the plans and say what colour he saw.
Justice Whata described the evidence as "being able to provide a lot of clarity to this case" if the colour of the paper road was decided upon. The findings would be presented to Justice Whata next week and his decision would be emailed to the respective lawyers.
