A call at last week’s Oban, Lorn and Isles Area Committee for an independent inquiry was defeated by just one vote.
Argyll and Bute Council’s Chief Executive apologised unreservedly in a letter to both remote communities for a flawed parking-management exercise but campaigners want to hear it in person.
Income the tickets in from Oban, Lorn and the Isles during that financial year could have ranged from £57,990 to £173,970.
Campaigners have crowfunded in readiness for this legal challenge which has now begun.
More than 6,000 parking tickets, or penalty charge notices were issued in Argyll and Bute during 2018, bringing in a total of £191,031.
The crowdfunding page at crowdfunder.co.uk/island-parking-tax-fighting-fund will give all pledges made by July 29 at 1.12pm to the appeal.

The petition calls on parliament to island proof transport infrastructure by banning councils from charging people to park at island lifeline ferry ports such as Fionnphort.
