United States District Court, D. Nevada
ORDER DIRECTING SUMMARY JUDGMENT REBRIEFING AND VACATING FEBRUARY 2,
2015, HEARING 
JENNIFER A. DORSEY, District Judge.
This coverage dispute arises from the Seneca Falls construction-defect litigation. Plaintiff United National Insurance Company seeks reimbursement of the $900, 000 it paid as the excess insurance carrier on a construction-defect settlement, alleging that the burden should have been borne instead by Assurance Company and Maryland Casualty Company ("Zurich").
Pending before the court is United National's motion for summary judgment, which has-so far-spawned 18 filings by the parties that total a remarkable 364 pages of briefs, not including exhibits. In preparing for the oral argument I set on this motion, I discovered that both sides have failed to comply with the local rules governing the format for summary-judgment briefing. Local Rule 7-4 limits summary-judgment motions and oppositions to 30 pages and replies to 20 pages each. And Local Rule 56-1 clarifies that the statement of facts supporting a motion for summary judgment or the responsive briefing must be "concise" and "include[d]" in the motion or response itself, not filed separately. Both United National and Zurich have completely ignored these rules:
United National's motion is 32-pages long. It would only barely exceed the permitted page limitation had United National not separately filed a 13-page supporting statement of facts in violation of Local Rule 56-1,  and another 3-page request for judicial notice, for a total of 48 pages of facts and argument, exclusive of exhibits.
Zurich responded with a 55-page opposition to the motion for summary judgment, a 45-page opposition to the statement of facts, a 12-page evidentiary objection, and a 21-page motion to strike one of United National's affidavits. Although Zurich asked for leave to file its 55-page opposition, it characterized that brief as just 41-pages long and thus conveniently failed to mention the additional, separately filed 78 pages of facts and objections -all of which are part of Zurich's summary-judgment-opposition package and collectively bring the total page count for the opposition to 133 pages before I even begin to consider exhibits.
United National's reply brief is a rule-compliant 20 pages-until I consider its separately filed 62 pages of reply facts, which brings the page count to 82 pages. United National never sought leave to file any oversized brief or to separate out its facts from its arguments in violation of Local Rule 56-1 and, indeed, it opposed Zurich's requests for over-length briefing as unnecessary.
A. The remedy for the parties' failure to comply with the local rules
"The Local Rules, adopted pursuant to Federal Rule of Civil Procedure 83, are laws of the United States." Federal "statutes and Rule 83 leave no room to doubt that the District Court [is] lawfully authorized to prescribe its local rules and that they have a clear legislative base." United National and Zurich have abused the summary-judgment procedure and blatantly ignored the clear rules of this court in their fractured and unnecessarily lengthy approach to briefing, and it would be judicially inefficient for me to consider these issues in their current format. It is well established that district courts have the inherent power to control their dockets and manage their affairs, and that includes the power to strike or deny motions as a sanction for abusive litigation conduct and violating court rules. I find that the most judicially economical way to manage this situation is to exercise my inherent power and deny United National's motion for summary judgment (Doc. 157) without prejudice to its refiling within the next 20 days in a format that fully complies with this order and the rules of this court. Once that motion has been filed, briefing will proceed in the normal course and in compliance with all the rules of the court and the directives of this order.
In opposing Zurich's request to file its oversized opposition, United National suggested that Zurich's submission was so long "in part because it spends so many pages engaging in unnecessary and inappropriate" ad hominem attacks, and some of the filings do reflect personal disputes between counsel. To be sure, summary-judgment briefs are not a canvas for the parties to display their personal grievances. The manner in which the parties have gone about this briefing (with United National completely ignoring the local rules and Zurich recognizing some of them but grossly understating the size of its full opposition when asking for additional pages) also does not warm the court to the idea that special treatment should be granted.
Nevertheless, in the interest of ensuring that the parties have a full and fair opportunity to present their proper arguments, I will enlarge the page limits as follows: the motion and response brief shall not exceed 40 pages-and the reply brief shall not exceed 25 pages-of facts, arguments, requests, and objections of any type. Separately filed statements of facts, requests for judicial notice, objections, or other components will not be permitted. Exhibits shall be filed in compliance with Local Rule 10-3. Any brief that exceeds the page limits found in Local Rule 7-4 must include a table of contents and table of authorities that will not count against the total page limit; these tables shall be paginated with lower case roman numerals (i, ii, iii), and the memorandum of points and authorities shall be paginated to begin on page 1. No additional enlargement requests related to the summary-judgment briefing will be considered. And further violations of the rules or this order will not be tolerated or excused; non-compliant filings will be struck without prior notice or an additional opportunity to conform to the rules. The parties are also cautioned that these constraints are not a license to move substantive arguments into single-spaced footnotes in 10-point font, expand margins, compress line spacing, or test other creative ways to evade the page limits; substantive arguments in footnotes will be disregarded.
Because I am granting leave to refile the summary-judgment briefs, and because the parties ask me to rule on this motion before deciding a pending joint motion to vacate a 2012 order,  I am also vacating the February 2, 2015, oral argument that was previously set on both motions. These matters may be rescheduled for hearing at the court's discretion once United National's renewed motion for summary judgment is fully briefed.
B. Admissible Evidence
Because the parties have leave for a do-over of this summary judgment process, I also take this opportunity to remind them that the summary-judgment procedure is the pretrial functional equivalent of a directed-verdict motion. It therefore requires the same caliber of evidence that would be admitted at trial. "[U]nauthenticated documents cannot be considered in a motion for summary judgment." To authenticate a document, the proponent ...
