Except this doesn't happen
And Northern did give all NL1 clubs criteria on grounds and fencing amongst other things for them to meet, this is despite some current NPL clubs not currently meeting all those requirements.
I'm not surprised West Wallsend are upset or Belswans. And unless North Lambton no longer have to share the ground with Athletics or they (or Northern) have got an alternative ground to use during summer then it appears Northern are happy to ignore their criteria. Which isn't a surprise considering Warners Bay got to keep their WPL team and Northern didn't want to wait any longer before changing it to WNPL
