Texas prisoner Edward E. Wesson instituted this civil rights action under 42 U.S.C. § 1983 against two named Texas Department of Corrections employees and “others unknown.” Proceeding pro se and in forma pauperis, Wesson raises claims of excessive use of force and denial of medical treatment, and seeks 120 million dollars in damages, as well as other relief, for the defendants’ alleged viоlations of his constitutional rights. The district court dismissed Wesson’s suit as frivolous under 28 U.S.C. § 1915(d) based on the recommendations of a United States, magistrate. Although we conclude that the district court’s findings are based on improper credibility determinations, we nevertheless affirm the court’s judgment based on our holding that Wesson has no arguable legal basis to support his claims of constitutional violations.
I.
Plaintiff-appellant Edward Eugene Wesson (Wesson) alleges in his pro se complaint, which we must construe liberally, that he was the victim of malicious and unprovoked assaults by Roy Oglesby (Oglesby) and Larry Turner (Turner), two prison officers employed by the Texas Department of Corrections (TDC). Wesson alleges that on September 29, 1988, he was sitting in the prison dayroom when Oglesby forced him into the main hall, placed him *280 against the wall, and put a “choke hold” on him that was so tight Wesson temporarily passed out. Immediately after this incident, Wesson was restrained with handcuffs and escorted to the prison infirmary by Turner. Wesson alleges that the handcuffs were applied so tightly that they caused his wrists tо swell and bleed.
Complaining of the treatment he received from Oglesby, Turner and others, Wesson filed a grievance with the TDC. The Internal Affairs Division (IAD) investigated the grievance and filed a report indicating that the incident in question arose when Ogles-by ordered Wesson to return to his cell. According to the IAD report, Wesson refused, arguing that he wanted a dose of his medication. Oglesby stated that he again ordered Wesson to his cell, telling him that he would receive his medication there. When Wesson again failed to comply, Oglesby took hold of Wesson’s arm, and Wesson struggled to pull free. Oglesby restrained Wesson and, with the help of other guards, placed Wesson in handcuffs. Prison records indicate that Wesson sustained no serious injury. The IAD concluded that the use of force under the circumstances was neither inappropriate nor excessive and ordered the investigation administratively closed.
Wesson filed this lawsuit
in forma pauperis
(IFP) in the district court on March 20, 1989. He pleaded causes of action under 42 U.S.C. § 1983,
1
claiming that the defendants violated his constitutional rights by using excessive force and by denying him medical care for the injuries he allegedly sustained as a result of the excessive force. Pursuant to 28 U.S.C. § 636(b), the district court assigned a United States magistrate to conduct an evidentiary hearing. Magistrate McKee held a
Spears
hearing,
see Spears v. McCotter,
Relying on
Whitley v. Albers,
Wesson objected to the magistrate’s findings, raising, among other things, the magistrate’s failure to address the issue of the defendants’ denial of medical treatment. The magistrate issued a supplemental report that addressed, and rejected, Wesson’s claim that he was unconstitutionally denied medical treatment. Wesson again objected; however, the district court, after purportedly conducting a de novo review, adopted the magistrate’s reports and dismissed the suit as frivolous. Wesson’s appeal is timely.
Wesson complains on appeal of the district court’s holding that he is required to show a serious injury. He argues that, if the use of force by prisоn guards is unnecessary, a constitutional violation is established regardless of the severity of a prisoner’s injuries. Wesson also contends, in broad, conclusory terms, that the district court erred in dismissing his § 1983 claim based on denial of medical treatment. We reject both of Wesson’s arguments.
II.
A. The Use of Credibility Assessments in 28 U.S.C. § 1915(d) Dismissals
Before we address the merits of Wesson’s аrguments on appeal, we are compelled to discuss the manner by which the magistrate arrived at his findings and recommendations. Our review of this record convinces us that the magistrate abused his discretion in conducting the Spears hearing *281 below by making credibility determinations based on disputed facts that were brought out at that hearing. The district court, in turn, fell short of conducting an adequate de novo review of the magistrate’s report after Wesson objected to the recommended findings. Nevertheless, as discussed below, we are able to affirm the district court’s judgment without resort to the magistrate’s credibility findings. Had this case presented a closer question on the legal viability of Wesson’s allegations, howеver, we would have been forced to vacate the court’s judgment and remand for further proceedings.
Congress enacted the IFP statute “to ensure that indigent litigants have meaningful access to the federal courts.”
Neitzke v. Williams,
[sjection 1915(d) is designed largely to discourage the filing of, and waste of judicial and private resources upon, baseless lawsuits that paying litigants generally do not initiate because оf the costs of bringing suit and because of the threat of sanctions for bringing vexatious suits under Federal Rule of Civil Procedure 11. To this end, the statute accords judges not only the authority to dismiss a claim based on an indisputably meritless legal theory, but also the unusual power to pierce the veil of the complaint’s factual allegations and dismiss those claims whose factual contentions are clearly baseless.
Neitzke,
490 U.S. at -,
District courts possess broad discretion in determining at any time whether an IFP suit is frivolous.
Wilson v. Lynaugh,
An IFP complaint that recites bare legal conclusions, with no suggestion of supporting facts, or that postulates facts of an entirely fanciful nature, is a prime candidate for dismissal-under § 1915(d). At the same time, howevеr, courts must construe
pro se
pleadings liberally.
Haines v. Kerner,
In
Cay v. Estelle,
A district court, faced with only the pleadings, and perhaps supporting affidavits, may consider credibility as a factor in determining frivolousness only to the extent that it believes a prisoner’s *282 allegations are almost impossible to prove, conflict with facts which may be judicially noticed, or postulate facts of a wholly fanciful kind. In addition, where witnesses can be observed and their testimony on direct and cross-examination compared, such as in a Spears hearing, credibility may be a factor only to the extent that a district court considers a complainant’s change of position when exposed to interrogation or conflicting evidence, major internal inconsistencies in a witness’s testimony, or substantial conflicts between the testimony of supporting witnesses.
Id. at 327.
The most important factor in § 1915(d) credibility assessments is “the inherent plausibility of a prisoner’s allegatiоns based on objective factors.”
Id.
at 326;
Gilbert v. Collins,
Applying these principles to the case at hand, we find that the magistrate abused his discretion by adopting the defendants’ version of material facts about which the parties clearly differed. Wesson alleged an episode of brutality that violated his rights under the eighth amendment, a scenario that was inherently plausible. To contradict Wesson’s allegations that Ogles-by and Turner inflicted needless discipline that caused Wesson an injury, the defendants submitted at the Spears hearing official TDC records showing that Wesson had disobeyed orders, that a major use of force was necessary to сontrol his recalcitrant conduct, and that he had sustained no injury-
In his Report and Recommendation, the magistrate did not find any of Wesson’s factual allegations to be “fanciful;” nor did he summarize any inconsistencies or conflicts within Wesson’s own complaint, testimony, or supporting evidence. For example, the magistrate did not suggest that Wesson rеcanted or modified his allegations when confronted with the TDC records at the Spears hearing. Rather, it is clear from his discussion that the magistrate simply accepted the credibility of the defendants’ proffered evidence as an accurate portrayal of the incident in controversy. Under Cay, this constituted a credibility assessment that the magistrate was not at liberty to make.
The district court, in turn, abused its discretion by adopting recommended findings that were clearly based on impermissible credibility assessments. Moreover, the court adopted the magistrate’s report and supplemental report apparently without benefit of a transcript or tape recording of the
Spears
hearing.
See Cay,
Considering the nascent stage of litigation at which this § 1915(d) dismissal occurred, thе proper procedure for the court in the scope of its de novo review would have been to accept as true those facts alleged by Wesson that were inherently plausible and internally consistent. The court then should have determined whether such facts were sufficient to survive the two grounds for IFP dismissals set out in Wilson and Pugh.
B. Wesson’s Claims
Although we disapрrove of the factfind-ing conducted by the district court in this case, we may nevertheless affirm the court’s judgment if we are able to conclude as a matter of law that, under the most liberal interpretation of Wesson’s complaint, his claims of excessive force and denial of medical treatment have no arguable merit.
*283
1. Excessive Force. For a prisoner to prevail in an excessive force claim, four elements must be proven: (1) A significant injury, which (2) resulted directly and only from the use of force that was clearly excessive to the need, the excessiveness of which was (3) objectively unreasonable, and (4) the action constituted an unnecessary and wanton infliсtion of pain. Huguet v. Barnett,
Wesson alleged below that Turner handcuffed him so tightly that his wrists were swollen and bleeding. There are no facts in the record, however, save Wesson's unsupported legal conclusions, to suggest that Turner's conduct constituted "an unnecessary and wanton infliction of pain," the fourth-and most important-Huguet element.
3
Wesson admits on appeal that "the handcuffs were applied carelessly." Carelessness, by definition, cannot amount to "wanton" conduct. Moreover, it is settled that negligenсe is insufficient to support a § 1983 claim. Daniels v. Williams, 474 U.s. 327, 329-36,
Looking, then, to Wesson's claim against Oglesby, Wesson alleged in his original complaint that, with the intent to "maliciously and sadistically inflict harm," Oglesby placed Wesson in a "choke hold" and applied sufficiеnt pressure to cause Wesson to briefly lose consciousness. Accepting for purposes of review Wesson's conclusory allegations that Oglesby's use of force was excessive, unreasonable, and malicious, we are left with what normally would be a difficult question: What quantum of harm constitutes a "significant injury" under the eighth amendment? We neеd not embark on this nebulous inquiry, however, because Wesson has abandoned on appeal his conteiition-if, indeed, he even raised such an `issue below-that he suffered a serious or permanent injury stemming from his momentary blackout.
4
He argues instead that "{ijf there is a complete absence' of justification for the application оf force, the intentional application of any force beyond de minimis is unconstitutional." This argument has been squarely addi~essed and rejected in Huguet,
2. Denial of Medical Treatment. Wesson alleged in his original complaint that "when plaintiff got to the unit hospital, they refused to give plaintiff medical treatment." Wesson did not specify who "they" referred to, although it is clear that Wesson did not name any infirmary employees as defendants. In his objections to the magistrate's findings, Wesson explained that the "defendants refused medical treatment by intentionally interfering with treatment."
To succeed in his claim under § 1983, Wesson must establish "deliberate indifference to serious medical needs." Estelle v. Gamble, 429 U.s. 97, 106, 97 5.Ct.
*284
285, 292,
We conclude that Wesson’s realistic chance of ultimate success in pursuing a § 1983 claim for denial of medical treatment arising from the alleged incident of excessive force rests between slight and nonexistent. We therefore affirm the district court’s dismissal under § 1915(d) of this claim.
III.
Based on the foregoing reasons, we AFFIRM the judgment of the district court.
AFFIRMED.
Notes
. Wesson also pleaded causes of action under state law; however, he did not object when the magistrаte failed to address these claims in his recommended findings, and has not briefed the issues on appeal. We therefore conclude that Wesson has waived review of these state law claims.
. Huguet borrowed the excessive force analysis developed under the fourth amendment in Johnson v. Morel,
. "[TJhe central inquiry in the Eighth Amendment context ... is whether the particular use of force amounts to the `unnecessary and wanton infliction of pain." Graham v. Connor, - U.S.-,
. Huguet was decided after the district court entered its final judgment dismissing Wesson's claim. However, even under prior Fifth Circuit precedent, see Shillingford v. Holmes,
. In his grievance filed with the TDC, Wesson alleged only swollen wrists.
