A. Upon the return of the report of the body determining just compensation and upon payment into court of the sum ascertained therein, the petitioner or its agents may enter and construct its works or improvements upon or through the property as described in its petition, notwithstanding the pendency of proceedings on any objections to such report in the trial court, or upon an appeal of the case, or the ordering of a new trial of the issue of just compensation or otherwise.
B. No order shall be made nor any injunction awarded by any court to stay the petitioner in the prosecution of its work unless it is manifest that the petitioner or its agents are transcending their authority and that the interposition of the court is necessary to prevent injury that cannot be adequately compensated in damages.
