Not ... nor

[bertietheblue]

From The Guardian newspaper:

"Collaboration can't overcome basic weaknesses in individual councils, nor stop them bringing forward badly designed projects."

Is this is a double negative?

Should it read:

"Collaboration can't overcome basic weaknesses in individual councils, or stop them bringing forward badly designed projects."

or:

"Collaboration can't overcome basic weaknesses in individual councils; nor can it stop them bringing forward badly designed projects."?

I prefer your versions.
