So here, presumably ?
https://maps.app.goo.gl/37375RyH2cgBB2S27GSV is Oct 2024, so very recent. Taxi broad yellow line in good condition, and sign in position, and this applies 24x7.
So please tell us more, like reason you parked on a well-signed taxi bay, or did you just chance your arm ?
There may be a 'technical' appeal based on the council management of the enforcement process, but I'll let others suggest it who are very knowledgeable in this aspect.
