Each of the school districts involved in this controversy are rural single school districts in Perry County, formed under general statutes of this State (Acts 1909, p. 947), and the territory of the two districts adjoins. On July 13,1914, the county court of Perry County made an order on the petition of electors, annexing to District No. 46, two tracts of land, constituting in all a section, adjoining the boundaries of that district and situated within the bounds of District No. 12. At that time District No. 12 was a common school district, but a petition had been filed and presented to the court asking for an election to be held for the purpose of converting the territory into a rural single school district. The petition was granted by the county court a few days after the order of annexation, and at the election subsequently held it was voted to constitute School District No. 12 a rural single school district.
The present proceedings originated in a petition filed in the county court on behalf of School District No. 12, at the October term, 1915, to cancel and set aside the order of annexation entered by the court on July 13, 1914.
The contention is that the order of annexation entered by the court was void for the reason that it appears from the evidence that the annexation reduced the number of children of scholastic age in District No. 12 below the statutory requisite of thirty-five, and also that the county court was not authorized to order the annexation of territory in another school district where a petition had already been filed to convert that district into a rural single school district. The court refused to cancel the original order of annexation, and on appeal to the circuit court the same order was entered there, from which an appeal to this court has been prosecuted.
*459The answer to both contentions on behalf of appellant School District .No. 12 is that this proceeding was not instituted within a reasonable time, and for that reason, if for no other, the relief should be denied. The present proceeding constitutes a collateral attack on the judgment of the county court and is analogous to a proceeding in a superior court by certiorari to quash the order of the county court. This court has repeatedly held that such an effort to quash a judgment in a matter involving public interest is not entertained as one of right, but is a matter of discretion, and unless the remedy is sought within, apt time it should be denied; the reason being that on account of the delay great public inconvenience may result in setting aside such an order. Johnson v. West, 89 Ark. 604. That principle applies with force to the present proceeding. The order of annexation was made in July, 1914, and the annexed territory became a portion of School District No. 46. No appeal was prosecuted from the order, and there was a delay of about a year and a half before the present proceedings were instituted to cancel the order of annexation. It cannot, therefore, be said that the petitioners proceeded expeditiously, and the delay is sufficient grounds to justify a denial of relief.
The judgment of the circuit court is, therefore, affirmed.
