UNITED STATES DISTRICT COURT

SOUTHERN DISTRICT OF FLORIDA

CASE NO. 21-cv-23275-ALTMAN/O’Sullivan

WILLIAM NUNEZ,

Plaintiff,

v.

COMMISSIONER OF SOCIAL 

SOCIAL SECURITY,

Defendant.

_________________________________________/

ORDER

The Plaintiff filed a Motion for Summary Judgment (the “Plaintiff’s Motion”) [ECF No. 21], 

seeking reversal of the ALJ’s decision and remand for further proceedings. The Defendant then filed 

its own Motion for Summary Judgment (the “Defendant’s Motion”) [ECF No. 26]. The Court referred 

both motions to Magistrate Judge John J. O’Sullivan. Judge O’Sullivan issued a Report and 

Recommendation (the “R&R”) [ECF No. 32], in which he recommended that (1) the Plaintiff’s 

Motion should be granted, and (2) the Defendant’s Motion should be denied. See R&R at 23. He also 

warned the parties as follows:

The parties have fourteen (14) days from the date of being served with a copy of this 

Report and Recommendation within which to file written objections, if any, with the 

Honorable Roy K. Altman, United States District Judge. Failure to file objections 

timely shall bar the parties from a de novo determination by the District Judge of an 

issue covered in the Report and shall bar the parties from attacking on appeal 

unobjected-to factual and legal conclusions contained in this Report except upon 

grounds of plain error if necessary in the interest of justice. See 28 U.S.C. § 636(b)(1); 

Harrigan v. Metro Dade Police Dep’t Station #4, 977 F.3d 1185, 1191-1192 (11th Cir. 

2020); Thomas v. Arn, 474 U.S. 140, 149 (1985); Henley v. Johnson, 885 F.2d 790, 794 

(11th Cir. 1989); 11th Cir. R. 3-1 (2016).

Id. at 23. Despite this warning, the parties have not timely objected to Magistrate Judge O’Sullivan’s

R&R. See generally Docket.

When a magistrate judge’s “disposition” has been properly objected to, district courts must 

review that disposition de novo. FED. R. CIV. P. 72(b)(3). But when no party has timely objected, “the 

court need only satisfy itself that there is no clear error on the face of the record in order to accept 

the recommendation.” FED. R. CIV. P. 72 advisory committee’s notes (citation omitted). Although 

Rule 72 itself is silent on the standard of review, the Supreme Court has acknowledged that Congress’ 

intent was to require de novo review only where objections have been properly filed—and not, as here, 

when neither party objects. See Thomas v. Arn, 474 U.S. 140, 150 (1985) (“It does not appear that 

Congress intended to require district court review of a magistrate [judge]’s factual or legal conclusions, 

under a de novo or any other standard, when neither party objects to those findings.”). In any event, 

the “[f]ailure to object to the magistrate [judge]’s factual findings after notice precludes a later attack 

on these findings.” Lewis v. Smith, 855 F.2d 736, 738 (11th Cir. 1988) (citing Nettles v. Wainwright, 677 

F.2d 404, 410 (5th Cir. 1982)).

The Court has reviewed the R&R, the record, and the applicable law, and can find no clear 

error on the face of the R&R. Accordingly, the Court hereby ORDERS AND ADJUDGES as 

follows: 

1. The R&R [ECF No. 32] is ACCEPTED and ADOPTED.

2. The Plaintiff’s Motion [ECF No. 21] is GRANTED. 

3. The Defendant’s Motion [ECF No. 26] is DENIED. 

4. The ALJ’s decision is REVERSED, and the matter is REMANDED to the 

Commissioner for further administrative proceedings.

5. The Court will enter final judgment pursuant to Rule 58 of the Federal Rules of Civil 

Procedure in a separate order. 

6. The Clerk of the Court shall CLOSE this case. All other deadlines are 

TERMINATED, and all other pending motions are DENIED as moot.
