1. While mandamus proceedings when instituted do not relate back to the time of the accrual of the right thereto, and the duty to be enforced must be a duty which exists at the time when the application fon the writ is made or the writ is granted, and if for any reason the duty no longer exists at the time the application is made, the writ must be denied (55 C. J. S. 108), and while a writ of mandamus will not in general be allowed, unless the act commanded to be done is legally possible before the writ issues

2. While under the ordinance of the City of Lyons which provides: “It shall be unlawful for any person to erect . . . any structure . . . or building ... of any sort . . . within the corporate limits of the City of Lyons, Georgia, without first submitting the plans for such building or structure to the mayor and councilmen, and receiving from them a permit in writing authorizing the erection of the same,” the verbal permission of the clerk of such municipality would not constitute a valid permit, and while the signatures of the individuals comprising the mayor and councilmen of the city, entered upon a written permit at a time when they were not acting in their official capacity, but merely as individuals, would not constitute a valid building permit, the evidence with respect to the plaintiff’s transaction with the clerk and his efforts to obtain the signatures of the individuals comprising the. mayor and councilmen upon a written permit, the exclusion of which is complained of in the first and second grounds of the amended motion for a new trial, was admissible as illustrating the plaintiff’s good faith and his contention that the defendants had acted arbitrarily, capriciously,' and unreasonably in refusing to grant such permit or to act thereon, and it was error to exclude it.
Judgment reversed.
