I have some experience with this in CA, and the delay may not be more than a couple of weeks (depending on the issues at hand). I have seen "cure and correct" re-votes done at immediately subsequent meetings.
As I was told by an attorney from the AG's office who came down to investigate a series of such accusations of violations by a local city council, The most common resolution to such matters is at the ballot box.
But, if you have the money and the cost of paying an attorney and going to court is worth it to you to make a point, that's your prerogative.
