                             ORDER AND JUDGMENT           *




Before EBEL , BALDOCK , and LUCERO , Circuit Judges.



         After examining the briefs and appellate record, this panel has determined

unanimously to grant the parties’ request for a decision on the briefs without oral

argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore

ordered submitted without oral argument.



*
      This order and judgment is not binding precedent, except under the
doctrines of law of the case, res judicata, and collateral estoppel. The court
generally disfavors the citation of orders and judgments; nevertheless, an order
and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
      Plaintiffs-appellants appeal from the district court’s denial, as untimely

filed, of their motion to alter or amend judgment made pursuant to Federal Rule

of Civil Procedure 59(e). Defendants urge dismissal of the appeal for lack of

jurisdiction because of an allegedly untimely filing of the Rule 59(e) motion.

Because plaintiffs’ motion was timely presented to the district court for filing, we

conclude that the district court had jurisdiction to consider the motion and reverse

and remand for consideration of the merits.

                                          I.

      The facts surrounding the presentation of plaintiffs’ motion to the district

court are undisputed. On November 27, 2001, plaintiffs’ courier timely presented

for filing a motion to amend the district court’s judgment. The motion was

presented to the district court. Although the proper district court case number

was on the face of the motion and the motion was entitled as one to the district

court, the case number in the caption was the number of the Tenth Circuit Court

of Appeals file. The clerk of the district court refused to file the motion and

instructed the courier to file it with the Tenth Circuit, which the courier did. But

the courier did not inform plaintiffs’ counsel that the district court refused the

filing or that the courier filed the motion with the Tenth Circuit. The State

responded to the motion in district court. When plaintiffs’ counsel finally

discovered that the motion had been filed in the wrong court, plaintiffs refiled the


                                         -2-
motion in district court with an explanation of the mix-up and the State’s

stipulation that it did not oppose the court’s consideration of the motion on the

merits.

       Nevertheless, the district court denied the motion as untimely filed,

concluding that it had no authority to enlarge the time for taking action under

Rule 59(e). While Federal Rule of Civil Procedure 6(b) does provide that a court

may not enlarge the period of time in which a motion must be filed under Rule

59(e), Federal Rule of Civil Procedure Rule 5(e) also prohibits the district court

clerk from refusing “to accept for filing any paper presented for that purpose

solely because it is not presented in proper form.” Fed. R. Civ. P. 5(e). Thus,

upon plaintiffs’ notice of its attempted timely filing, and having taken judicial

notice of the timely filing in the Tenth Circuit, the district court had the authority

to enter a nunc pro tunc order according the motion a filing date as of the date it

was originally presented to the clerk for filing.      Cf. Parissi v. Telechron, Inc.,   

, 47 (1955) (holding that failure to timely pay filing fee did not vitiate

validity of notice of appeal that was presented to clerk for filing within filing

period but not filed); Houston v. Lack , 

, 277 (1988) (holding that

notice of appeal was “filed” for jurisdictional purposes when petitioner delivered

it to prison authorities for forwarding to the court clerk);     Long v. United States

Dep’t of Air Force , 

, 342 (10th Cir. 1984) (holding that petition for


                                              -3-
review was timely “filed” when received by clerk within the time fixed for filing

even though it was not stamped as filed until clerk received filing fee and

certificate of service after filing period). Such action does not “enlarge” the

filing period but simply recognizes the timely presentation of the motion for filing

in the proper court. We conclude that the court erred in refusing to consider

plaintiffs’ motion to amend as untimely filed.

                                          II.

      The State alternatively argues that this court should affirm the district court

on the alternative ground that the district court could not grant the relief

requested in the Rule 59(e) motion because all contentions raised therein are

without merit under the doctrines of mootness, law of the case, and the mandate

rule. While we agree that plaintiffs’ request for a stay while certiorari was

pending is now moot, we reject the State’s assertion that the doctrine of law of

the case and the mandate rule require denial of plaintiffs’ underlying motion on

the merits.

      A. “Law of the case principles do not bar a district court from acting

unless an appellate decision has issued on the merits of the claim sought to be

precluded.”   Wilmer v. Bd. of County Comm’rs    , 

, 409 (10th Cir. 1995)

(quotation omitted). In denying plaintiffs’ motion to amend in our prior opinion,

we did not rule on the merits of that motion, but rather, declined to exercise our


                                          -4-
discretion to grant leave to amend. We emphasized that an             appellate court should

exercise its power to allow a plaintiff to add a party “sparingly.”         Thompson v.

Colorado , 

, 1025 n.2 (10th Cir. 2001),         cert denied , 

(2002) (quotation omitted). In declining to exercise our discretion, we

recognized that the standards used in considering motions to amend differ

drastically depending on the procedural posture of a case. Thus, while an

appellate court should add a party only “sparingly,” 

amend brought

in district court should be freely granted, see Fed. R. Civ. P. 15(a) (“leave [to

amend] shall be freely given when justice so requires”), unless the proposed

amendment would result in unfair prejudice to the non-movant or would be futile.

See Patton v. Guyer, 

, 86 (10th Cir. 1971) (prejudice); Drake v. City

of Fort Collins, 

, 1163 (10th Cir. 1991) (futility). These factors

likewise control resolution of a motion to amend considered by a district court

after a remand.

       The principal factors which are considered in connection with the
       offer of an amendment [after remand] are, first, whether it will cause
       delay and, second, whether the adversary will suffer prejudice.
       Lateness does not of itself justify the denial of the amendment. And
       the fact that it is offered following remand does not suffice of itself
       to require denial. Unless the granting of the amendment after remand
       caused grave prejudice, the action is not an abuse of discretion.

       R.E.B., Inc. v. Ralston Purina Co., 

, 751-52 (10th Cir. 1975).

Because the first Thompson panel did not analyze prejudice to the State, lateness,


                                             -5-
or futility, and based its ruling more on the procedural posture of the case than on

a merits determination, “the law of the case doctrine does not reach through . . .

to enshrine a substantive determination never in fact made.” 

.

       B. The State’s argument regarding the mandate rule is intertwined with its

law-of-the-case argument. The mandate rule requires             a district court to “comply

strictly with the mandate rendered by the reviewing court.” Huffman v. Saul

Holdings Ltd. P’ship, 

, 1132 (10th Cir. 2001) (holding that district

court had no authority to grant motion for appeal-related fees after appellate court

had expressly denied motion for those fees) (quotation omitted). The State argues

that, applying Huffman, the district court’s authority to consider a motion to

amend on remand is likewise foreclosed by the mandate denying the motion to

amend on appeal. Again, we disagree.

       Huffman is distinguishable because “application for appellate fees must

first be made to our court,”   

while motions to amend a complaint

should normally be brought in a district court. Further, in         Huffman , we ruled on

the merits of the motion for appellate fees,         see 

here, we simply refused

to exercise our discretion in part because of the procedural posture of the case.

       We recently re-emphasized that, while a district court is “bound to          follow

the mandate, and the mandate ‘controls all matters within its scope, . . . a district


                                               -6-
court on remand is free to pass upon any issue which was not expressly or

impliedly disposed of on appeal.’” Procter & Gamble Co. v. Haugen, ___ F.3d

___,___, 

, at *3 (10th Cir. Jan 6, 2003) (quoting Newball v.

Offshore Logistics Int’l, 

, 826 (5th Cir. 1986). In declining to

exercise our discretion to allow amendment, we did not preclude the district court

from exercising its discretion to do so on remand. To the contrary, we noted that

plaintiffs had neither “alleged nor shown that denial of the motion results in an

advantage lost by the Plaintiffs or disadvantage incurred.”    

n.2. In other words, we refused plaintiffs’ request in part because our denial

of the motion to amend would not be to plaintiffs’ ultimate detriment or prejudice

them after remand.

       If we were to now foreclose the district court from considering a motion to

amend on its merits, plaintiffs would be unfairly disadvantaged in a way clearly

not contemplated by, and contrary to the express language of, the mandate.     All

the mandate required was that the district court grant summary judgment to the

State on the issue of sovereign immunity and dismiss it as a defendant. It would

not be contrary to the mandate to allow plaintiffs to amend their complaint or,




                                            -7-
alternatively, to add Mr. Fisher in his official capacity as a defendant pursuant to

Federal Rule of Civil Procedure 21 1, before doing so.

                                            III.

       The State claims that the district court’s order is not a final, appealable

order due to the fact that the district court has not ruled on the State’s Motion for

Extension of Time to File a Bill of Costs. But any argument that the appeal

should be dismissed based on this erroneous contention is frivolous.           See Fed. R.

Civ. P. 58 (“[e]ntry of the judgment shall not be delayed, nor the time for appeal

extended, in order to tax costs or award fees.”);    Buchanan v. Stanships, Inc.     , 

, 268 (1988) (“[A] request for costs raises issues wholly collateral to the

judgment in the main cause of action.”);      Tyler v. City of Manhattan     , 

, 1402 n.1 (10th Cir. 1997) (“The fact that the original judgment left open

the issue of costs and attorney fees did not deprive the judgment of finality for

purposes of appeal.”) (citing    Budinich v. Becton Dickinson & Co.        , 

,

202 (1988)).

       Rule 21 provides that “[p]arties may be . . . added by order of the court on
motion of any party or of its own initiative at any stage of the action and on such
terms as are just.” Resort to Rule 21 is appropriate where, as in this case,
“requiring dismissal after years of litigation would impose unnecessary and
wasteful burdens on the parties, judges, and other litigants waiting for judicial
attention.” Newman-Green, Inc. v. Alfonzo-Larrain, 

, 836 (1989).

      The State’s motion to dismiss the appeal is DENIED. The judgment of the

United States District Court for the District of Colorado is REVERSED, and the

case is REMANDED for consideration of plaintiffs’ motion to alter or amend the

judgment.
