The club had to re-submit their plans, originally agreed almost two years ago, to make sure they conformed to new planning law.
At a meeting of Liverpool council's planning committee today those plans were once again given the go-ahead.
Approval could have been taken by council officials but it is believed a decision was made for it to go back before the planning committee to allow transparency, and objectors to put their views again.
Liverpool have major financial problems to overcome, however, with the cost of the Stanley Park venture having spiralled to £160m.
At the clubs recent AGM, it was said that completion of the work on the new stadium could take up to four years.
The club, who insist they are still actively looking for outside investment, have denied claims that they have lost £11m in European Union grants. A decision on that is expected next month.
