This case was oiginally brought by J. P. Hass •ct al., plaintiffs in error, as plaintiffs, against. J. A. McCampbell, city clerk of the city of Anadarko, in the.district court- of Caddo •county to restrain him from issuing warrants and certifying to the county clerk of that county an assessment made by the city- coun *291 cil against certain property to pay for sidewalks constructed along its front. At the .commencement of the action a temporary restraining order issued which on October 9, 1908, was dissolved, to reverse which, after superseding'the order, plaintiffs on November 9, 1908, commenced proceedings in error in this court. After failing to observe rule 7 by serving their brief on counsel for defendant in error within 40 days after filing their petition in error, plaintiffs in error, on January 19, 1910, asked for and .obtained leave of this court to file said brief in 60 days. On their failure so to do defendant in error, on April 19, .1910, filed.motion to dismiss and served plaintiffs-in error with a copy. Eor some reason this motion was not passed on, although unopposed. On March' 16, 1910, plaintiffs in -errorwithdrew -the record in this cause from this court and failed to return the same until 'September 5, 1910, and on September 7, 1910, filed briefs herein..

This case was set for submission and was submitted on September 13, 1910, just six days after plaintiffs in error filed their briefs. Under the rules, defendant in error is entitled to 30 days after plaintiff in error files his briefs in which to file his briefs. It follows that, if plaintiffs in error’s briefs are now to be considered, which were filed without permission of the court, the final determination of this case must still be further delayed.

Defendant in error insists that, pursuant to his motion for failure to file briefs, this cause, should be dismissed. We think so too, and, as no excuse is attempted to be shown for this flagrant violation of rule 7 (20 Okla. viii, 95 Pac. vi), this'petition in error is dismissed.
