However this will not happen if I am right and Section 3(4) of the GPDO 1995 applies to any condition of any permission even those which have not been implemented
You don't implement conditions, you implement planning permissions keeping within the conditions they may impose. If you don't implement the permission, you cannot be held to be complying or subverting the conditions
Extending the house and shed analogy:
You have a piece of land that already has some permitted dev right for a small shed, and there is no house there
You apply for two different permissions because you cannot make up your mind
One permission is for a big house, it is granted but a condition says "thou shalt not build any shed"
One permission is for a small house, it has no condition mentioning a shed
..a big house and a shed, in that order -> you're in breach of the condition of the permission for the big house
..a shed and a big house, in that order -> you're not in breach, because at the time the shed was built the big house permission was not implemented or even started. its conditions cannot be held to apply
..a small house and a shed, in any order -> you're not in breach
..a medium house of a style that combines bits from both of your two permissions, and a shed -> you've carried out unlawful development with regard to the house as you have no planning permission for it, and the shed is fine because you were allowed to build it independently of the big house permission that confiscated it (which does not apply because you didn't build a big house)
You must appreciate that you can have 2 planning permissions current and active on a plot of land; you may build either or none but you cannot build both. It is thus as Nakajo says, not the granting of permission that binds you, but the implementing of it. I have 3 permissions for my plot, each one saying I must pay the council umpteen thousands of pounds in S106 bribes to implement it. The council acknowledge that just because they have granted the permission, the money is not due until I start on one of the schemes at which point I will owe the amount relevant to that scheme.
Ultimately, the only body remotely intersted and having the authority to do anything about your complaint, has given you their view: the conditions do not apply because the permission they're attached to has not been implemented so they don't care
You're on a hiding to nothing. Take up a useful pass-time such as volunteering at your local homeless shelter, and leave your neighbours alone
