dissenting:
I respectfully dissent, and would affirm.
We review summary judgment de novo, and can affirm on any ground.1 I agree with the majority that proof of service creates only a rebuttable presumption of receipt, and that the presumption can be rebutted by a credible sworn declaration of non-receipt. Nevertheless, on the record in this case, the court properly applied Federal Rule of Civil Procedure 36, deeming the requests for admission admitted and declining to allow them to be withdrawn.
The requests for admission were mailed August 9, 2010. No response was ever made. Of course it is conceivable that the Post Office erred, or that an error was made by the staff in the law office representing the defendants, so that defense counsel never saw the requests shortly after mailing. That would not matter to whether Rule 36(a)(3) should be applied, because defendants were given notice of the requests on at least two subsequent occasions and still failed to respond.
Plaintiffs counsel filed a report with the court October 12, 2010 and served it on defense counsel, saying that “Plaintiff propounded written discovery to defendants, including requests for admission.” Defense counsel never denied receipt. After being served with this report, the defense knew very well that plaintiff was claiming that requests for admission had been served, yet neither asked for another copy nor offered any response.
Plaintiffs counsel asked defense counsel on November 2, 2010 why “she had never responded to any of the written discovery.” She “did not deny having received the discovery” and did not ask for copies or for more time to respond. Thus it does not matter whether defense counsel received the requests for admission mailed August 9. They were advised in October and November of the outstanding discovery requests and still failed to respond.
The Fourth Circuit declined to allow withdrawal of admissions in a similar case where a certificate of service showed that the requests for admission were properly *737mailed, but the defendant swore in an affidavit that she had not received them.2 In that case, the defendant heard a reference to the requests for admission during trial, but made no objection and did not claim that she had not received them.3 The court ruled that “[i]t would be an intolerable obstruction to the administration of justice if a party should be permitted to remain silent ... and subsequently, after judgment had gone against him, to question for the first time the regularity of the proceedings.”4 The administration of justice is no less obstructed here, where defendants ignored repeated advice of the outstanding discovery until after plaintiff relied on the non-response to prepare a motion for summary judgment.
Unanswered written discovery was not the first, or only, instance of the defendants’ avoidance of discovery. The owner and operator of the assisted living care facility being sued had obtained a delay of his deposition for a family emergency requiring him to go to Pakistan, and then did not go to Pakistan because the sick relative had died. Two days before his rescheduled deposition, he met with the plaintiff in the absence of plaintiffs attorney and appears to have gotten plaintiff to sign something purporting to settle the case for much less than it was worth. Plaintiffs lawyer disputes that the plaintiffs signature on the letter is authentic and offered credible evidence showing that defense counsel was involved in mailing the letter. Like the failure to respond to written discovery, avoidance of the deposition suggests that the defense chose intentionally not to comply with its discovery obligations.
The district court did not abuse its discretion in refusing to allow the requests to be withdrawn, even though its articulation of the reason was imperfect. The defendants never moved to withdraw the admissions as required by Rule 36(b). There was no motion to deny, so denial could not be an abuse of discretion. The Fifth Circuit has held that withdrawal under Rule 36(b) requires a motion, and that a district court’s withdrawal of admissions without a proper motion was an abuse of discretion.5 Though defendants, in their opposition to the motion for summary judgment, argued against treating the requests as admitted, they still did not lodge a proposed response. The least the court was entitled to as a predicate for discretionary relief was a response showing what was admitted and what was not admitted.
Even had a proper motion been filed, with a response provided, plaintiff would have been prejudiced had the district court allowed withdrawal of the admissions. Rule 36(b) gives a judge discretion to permit withdrawal of admissions “if the court is not persuaded that it would prejudice the requesting party in maintaining or defending the action on the merits.” Here, the requesting party, Seminiano, would be prejudiced by withdrawal of the admissions. Defendants repeatedly evaded attempts to depose the owner of the facility, and completely ignored the written discovery requests. By the time defendants responded to the motion for summary judgment, discovery had closed, and plaintiff would have had no way to prepare his case *738for trial. Under Cordon v. United States,6 the district court did not abuse its discretion by not allowing withdrawal of the admissions.
In this circumstance, even though the presumption of receipt from proof of service is rebuttable, it is hard to imagine a reasonable decision other than to treat the requests for admission as admitted. The defense was informed of the requests twice subsequent to the initial service, never responded, never moved for relief, never said what responses it would have made, and otherwise appears to have evaded its discovery obligations. This is a lawsuit to collect overtime wages by an apparently poor worker at a nursing home. Inexpensive written discovery is about the only economical way such a lawsuit can be pursued. By emasculating written discovery, we empower economically better off bullies seeking to starve out poorer plaintiffs by forcing them to bear litigation expense one side can bear better than the other. The record supports the judgment even though In re Bucknum7 is not good authority for it. The district court did not abuse its discretion in treating the unanswered requests for admission as admitted. We ought to affirm the reasonable award and attorney’s fees in full.
