THe signs seem clear enough for a head-on approach. With GSV not up-to-date we have to rely on you doing some legwork to determine the extent of the signage.It is now normal for advance warning signs to be erected, especially for a right or left turn into the street with the restriction. So there really should be an advance sign on the approach, but you'll need to go and see if there is one if you want to build a stronger case.
Arguing about no notice of a new restriction is not a hugely strong argument, but may be worth it, assuming you are reasonably local, so do submit reps stating that some forewarning of the restriction should have been put out to local residents, such as signs on the approach. If it was only a week ago the restrictions came in then I would emphasise this.
The problem you have is that it doesn't matter what you submit to the council, they will reject it. They do this because they know that circa 95% of people then just cough up. If you take them to London Tribunals after their inevitable rejection it will be with the full PCN penalty in play.
As this is Newham, there may be a 'technical' appeal based on Newham mismanagement of the enforcement process, but I'm not up to speed on these. However Hippocrates who posts on this forum has become something of a 'guru' on these, but again, I must emphasise that such appeal arguments only get a real consideration at London Tribunals.
