We think this question requires an affirmative answer. It is shown that appellant was the successful bidder to construct the incinerator and that it was awarded the contract subject to sale of the certificates validated by this Court in State v. City of Miami, Fla., 55 So.2d 715. It is essential that this and any other question as to right to proceed with the construction be removed. It is further revealed from the record that there is no material difference in the parties, the issues involved and the purpose of this suit and the other two suits referred to in the forepart of this opinion. The record further shows that the City Commission and the Planning Board have taken all steps necessary and performed all prerequisites required by Section 72 and other provisions of the City Charter essential to construction of the incinerator.
