opinion: Per Curiam.
  Respondent Jerry Mack Dorrough was convicted in 1963 in a Texas District Court of robbery and sentenced to a term of imprisonment for 25 years. After he was sentenced and had filed an appeal to the Texas Court of Criminal Appeals, he escaped from the Dallas County jail by stealing a federal mail truck. He was recaptured two days after his escape. After his recapture, the Texas Court of Criminal Appeals removed his appeal from its docket pursuant to the provisions of Texas Code of Criminal Procedure Ann., Art. 44.09 (1966), which provides for the automatic dismissal of such pending appeals by an escaped felon upon escape with provision for reinstatement of the appeal if the felon voluntarily surrenders within 10 days of his escape.
  After recapture, respondent was tried and convicted on federal charges and given a 25-year federal sentence which he is currently serving. The State of Texas has filed a detainer warrant with federal authorities against Dor-rough in order to compel him to serve the remainder of his state sentence upon release from federal custody. In 1972, respondent filed in the United States District Court for the Northern District of Texas a complaint which was treated by that court as a petition for writ of habeas corpus, alleging that the 1963 dismissal of his appeal under Art. 44.09 denied him equal protection of the law in violation of the Fourteenth Amendment. The United States District Court denied relief, holding that Art. 44.09 was a rational exercise of legislative power. The United States Court of Appeals for the Fifth Circuit reversed. It held that Art. 44.09 denied respondent equal protection of the law, and ordered that the State's de-tainer warrant would be voided unless Texas provided respondent with either a direct appeal or a new trial. Petitioner has now sought review by certiorari, pursuant to 28 U. S. C. § 1254 (1), of the judgment of the Court of Appeals. For the reasons stated, we grant the writ and reverse the judgment.
  The Court of Appeals correctly recognized that there is no federal constitutional right to state appellate review of state criminal convictions. McKane v. Durston, 153 U. S. 684, 687 (1894); Griffin v. Illinois, 351 U. S. 12, 18 (1956); Ross v. Moffitt, 417 U. S. 600, 610-611 (1974). Disposition .by dismissal of pending appeals of escaped prisoners is a longstanding and established principle of American law. 18 Geo. Wash. L. Rev. 427, 429 (1950). This Court itself has long followed the practice of declining to review the convictions of escaped criminal defendants. Smith v. United States, 94 U. S. 97 (1876) ; Bonahan v. Nebraska, 125 U. S. 692 (1887); Eisler v. United States, 338 U. S. 189 (1949); id., at 883; cf. Allen v. Rose, 419 U. S. 1080 (1974). Thus in Molinaro v. New Jersey, 396 U. S. 365 (1970), we dismissed the appeal of an escaped criminal defendant, stating that no persuasive reason exists to adjudicate the merits of such a case and that an escape “disentitles the defendant to call upon the resources of the Court for determination of his claims.” Id., at 366. In Allen v. Georgia, 166 U. S. 138 (1897), we upheld as against a constitutional due process attack a state court’s dismissal of the appeal of an escaped prisoner and its refusal to reinstate the appeal upon his later recapture. See also National Union v. Arnold, 348 U. S. 37,43 (1954).
  The Texas courts have found similar ends served by Art. 44.09. It discourages the felony of escape and encourages voluntary surrenders. It promotes the efficient, dignified operation of the Texas Court of Criminal Appeals.
  The Court of Appeals, however, found two classifications created by the statute to lack any rational relation to its purposes and hence concluded that the statute was unconstitutional as violative of the Equal Protection Clause. That court recognized that appeals from state criminal convictions are not “explicitly or implicitly guaranteed by the Constitution,” San Antonio Independent School District v. Rodriguez, 411 U. S. 1, 33-34 (1973), and that this Court in dealing with equal protection challenges to state regulation of the right of appeal in criminal cases had applied the traditional rational-basis test. Rinaldi v. Yeager, 384 U. S. 305 (1966). There this Court said:
  “ 'The Constitution does not require things which are different in fact ... to be treated in law as though they were the same.’ Tigner v. Texas, 310 U. S. 141, 147. Hence, legislation may impose special burdens upon defined classes in order to achieve permissible ends. But the Equal Protection Clause does require that, in defining a class subject to legislation, the distinctions that are drawn have 'some relevance to the purpose for which the classification is made.’ Baxstrom v. Herold, 383 U. S. 107, 111; Carrington v. Rash, 380 U. S. 89, 93; Louisville Gas Co. v. Coleman, 277 U. S. 32, 37; Royster Guano Co. v. Virginia, 253 U. S. 412, 415.” Id., at 309.
  The Court of Appeals thought that this test rendered the statute invalid for two reasons. First, while the statute provides for reinstatement of the appeal of most escaped felons only if they voluntarily surrender within 10 days, the Texas Court of Criminal Appeals may in its discretion reinstate the appeals of prisoners under a sentence of life imprisonment or death if they are returned to custody within 30 days. Second, the statute applies only to those prisoners with appeals pending at the time of their escape; prisoners who have not invoked the appellate process by filing an appeal at the time of their escape may still appeal after recapture if applicable appellate time limits have not run. We disagree with the analysis of the Court of Appeals, and find that neither of these distinctions offends the Equal Protection Clause.
  Insofar as the separate treatment of prisoners under a sentence of life imprisonment or death is concerned, we see no reason why the Texas Legislature was not free to separate these two most severe sentences from other terms of imprisonment, and provide an additional period of discretionary review for them but not for the remainder. The Court of Appeals determined that under Texas law a prisoner serving a sentence for a term greater than 60 years would not be eligible for parole any sooner than a prisoner under life sentence, and from that fact concluded that there could be no rational distinction between those serving a life term and those serving a term in excess of sixty years. 497 F. 2d 1007, 1012-1013. It is not altogether clear how respondent, who himself has been sentenced to 25 years, could assert the rights of those under term sentences of 60 years or more. But apart from this difficulty, we see no reason why the Texas Legislature could not focus on the actual severity of the sentence imposed in making distinctions, rather than on the collateral consequence of sentence elaborated by the Court of Appeals. The State of Texas could reasonably balance its concern with deterring escapes and encouraging surrenders with its alternative interest in allowing the validity of particularly severe sentences to be tested by appellate review. In doing so, it was not required to draw lines with “mathematical nicety.” Lindsley v. National Carbonic Gas Co., 220 U. S. 61, 78-79 (1911); Morey v. Doud, 354 U. S. 457, 463-64 (1957).
  Nor do we find the statutory limitation of the dismissal requirement to those prisoners with appeals pending at the time of their escape violative of the Equal Protection Clause. The Court of Appeals felt that the statute was “underinclusive” for this reason, since a prisoner who had not invoked the appellate process by filing an appeal at the time of his escape might still appeal after recapture if the prescribed time for filing an appeal had not expired.
  Criminal defendants in Texas are subject to relatively stringent time limits for filing their appeals. Since an escaped defendant cannot comply with the required appellate steps during the time he is not confined, these time limits serve much the same function as Art. 44.09. Whatever difference in treatment exists between the class of prisoners who escape, return, and are nonetheless able to file an appeal, and those whose appeals are dismissed pursuant to Art. 44.09, is sufficiently rational to withstand a challenge based on the Equal Protection Clause. Texas was free to deal more severely with those who simultaneously invoked the appellate process and escaped from its custody than with those who first escaped from its custody, returned, and then invoked the appellate process within the time permitted by law. While each class of prisoners sought to escape, the first did so in the very midst of their invocation of the appellate process, while the latter did so before returning to custody and commencing that process. If Texas is free to adopt a policy which deters escapes by prisoners, as all of our cases make clear that it is, it is likewise free to impose more severe sanctions on those whose escape is reasonably calculated to disrupt the very appellate process which they themselves have set in motion. Ross v. Moffitt, 417 U. S., at 610.
  The motion of respondent for leave to proceed in forma pauperis and the petition for certiorari are granted, and the judgment of the Court of Appeals for the Fifth Circuit is
  Reversed.
  Me. Justice Douglas, dissenting, agrees with much of the dissenting opinion of Mr. Justice Stewart, but unlike him, would also affirm the judgment for the reasons stated by the Court of Appeals, 497 F. 2d 1007, 1012-1014 (CA5 1974).
  Texas Code of Criminal Procedure Ann., Art. 44.09, provides:
  “If the defendant, pending an appeal in the felony case, makes his escape from custody, the jurisdiction of ’the Court of Criminal Appeals shall no longer attach in the case. Upon the fact of such escape being made to appear, the court shall, on motion of the State’s attorney, dismiss the appeal; but the order dismissing the appeal shall be set aside if it is made to appear that the defendant has voluntarily returned within ten days to the custody of the officer from whom he escaped; and in cases where the punishment inflicted by the jury is death or confinement in an institution operated by the Department of Corrections for life, the court may in its discretion reinstate the appeal if the defendant is recaptured or voluntarily surrenders within thirty days after such escape.”
  This provision was adopted by Texas in 1879 replacing a somewhat similar common-law rule discussed in Ex parte Wood, 19 Tex. Ct. App. 46 (1885). The clause authorizing discretionary reinstatement of an appeal from a sentence of death or life imprisonment was added by amendment in 1933. Laws 1933, c. 34. Since the statute provides that jurisdiction shall “no longer attach” upon escape, the escape itself divests the court of jurisdiction with later dismissal being a mere formality. Lafferty v. State, 123 Tex. Cr. R. 570, 60 S. W. 2d 222 (1933); Ex parte Gurley, 104 Tex. Cr. R. 578, 286 S. W. 222 (1926).
  Braden v. 30th Judicial Circuit Court of Kentucky, 410 U. S. 484 (1973), indicates that one under a state detainer warrant is considered to be in custody for the purpose of federal habeas relief. The District Court concluded that respondent had properly exhausted his state remedies, and the petitioner did not urge failure of exhaustion in the Court of Appeals.
  The only contention presented to the District Court as evidenced by its opinion was the constitutionality of Art. 44.09 discussed herein. Respondent seeks here to raise other issues not raised below, at least some of which were considered and rejected by other courts during the course of his five prior actions in the federal system. See 327 F. 2d 667 (CA5 1964); 344 F. 2d 125 (CA5 1965); 397 F. 2d 811 (CA5), cert. denied, 394 U. S. 1019 (1969); 440 F. 2d 1063 (CA5), cert. denied, 404 U. S. 840 (1971); 440 F. 2d 1336 (CA5), cert. denied, 404 U. S. 915 (1971).
  The decision of the District Court is unreported. The decision of the Court of Appeals is reported at 497 F. 2d 1007.
  Rodriguez v. State, 457 S. W. 2d 555, 556 (Tex. Crim. App. 1970).
  Loyd v. State, 19 Tex. Ct. App. R. 137, 155 (1885). See also 18 Geo. Wash. L. Rev. 427, 430 (1950).
  497 F. 2d, at 1012-1013. The court below specifically rejected the notion that immediate dismissal with refusal to reinstate appeals of escaped defendants was constitutionally objectionable and rested its decision wholly on the asserted lack of rational connection between the statutory classifications and the statute’s purposes.
  But our Brother StewaRT resurrects this rejected argument and adopts it in his dissent, saying that the Texas statute may not rationally be said to discourage the felony of escapo and encourage voluntary surrender. Such a judgment, of course, is one in the first instance for the legislature, Williamson v. Lee Optical Co., 348 U. S. 483 (1955), and we may strike down such a legislative judgment only if we conclude that it is indeed irrational. We do not believe that it is. Nor is it accurate to suggest that the only purpose served by the Texas statute is the deterrence of escapes: it is also designed to secure the State’s interest in orderly judicial procedure. The right of appeal from a judgment of conviction in both the federal and state systems is almost uniformly conditioned, for example, upon the filing of a notice of appeal within a prescribed time limit. See Fed. Rule App. Proc. 4 (b); n. 10, infra. The vindication of orderly procedure secured by the Texas statute under attack here is no less a permissible choice for the legislature than is the vindication of that interest by such procedural requirements. In a case indistinguishable from the present one on this issue, this Court in Allen v. Georgia, 166 U. S. 138, 141 (1897), upheld the refusal of the Georgia courts to reinstate the appeal of a recaptured prisoner, stating that “it seems but a light punishment for such offence to hold” that he has abandoned such appeal.
  See n. 1, supra. The statute merely allows the court in its discretion to reinstate such appeals. In the past, the court has both granted leave to reinstate and refused it under a test of “good cause shown.” Bland v. State, 224 S. W. 2d 479 (Tex. Crim. App. 1949); Foster v. State, 497 S. W. 2d 291 (Tex. Crim. App. 1973).
  Cf. United States v. Raines, 362 U. S. 17, 21-24 (1960).
  See Tex. Code of Crim. Proc. Ann., Arts. 40.05, 40.09 (1966 ed., and Supp. 1974-1975), 44.08 et seq. For example, in the cases cited by the lower court as involving pre-appeal escapes with subsequent appeals, the appellants forfeited substantially all of their appeal rights through failure to file a timely record or bill of exceptions. Webb v. State, 460 S. W. 2d 903 (Tex. Crim. App. 1970); McGee v. State, 445 S. W. 2d 187 (Tex. Crim. App. 1969). In Texas the trial judge has the power to file the record with the Court of Criminal Appeals and if he does so prior to recapture of an escaped prisoner, the appeal is dismissed under Art. 44.09. Webb v. State, 449 S. W. 2d 230 (Tex. Crim. App. 1969); Redman v. State, 449 S. W. 2d 256 (Tex. Crim. App. 1970); Ballage v. State, 459 S. W. 2d 823 (Tex. Crim. App. 1970).
  The peculiar problems posed by escape of a prisoner during the ongoing appellate process were explored in Loyd v. State, 19 Tex. Ct. App. R., at 155, in the course of upholding the constitutionality of this statute:
  “[L]et us suppose that the convict, pending his appeal, should escape and remain at large twenty or thirty days; what disposition should be made of his appeal? . . . Should this court wait until his return to custody? How long must it wait? Until it suits the prisoner’s convenience? . . . [W]e are of the opinion that [Art. 44.09] is not only reasonable but eminently wise.”

instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the ideological "direction" of the decision ("liberal", "conservative", or "unspecifiable"). Use "unspecifiable" if the issue does not lend itself to a liberal or conservative description (e.g., a boundary dispute between two states, real property, wills and estates), or because no convention exists as to which is the liberal side and which is the conservative side (e.g., the legislative veto). Specification of the ideological direction comports with conventional usage. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. In interstate relations and private law issues, consider unspecifiable in all cases.
