We granted certiorari to review the decision of the Colorado Court of Appeals in
People v. Marquiz,
685 P.2d 242 (Colo.App.1984), sustaining the defendant’s convictions for first-degree murder and conspiracy to commit first-degree murder. We limited our review, however, to the issue of whether the defendant, Steven Richard Marquiz, could be convicted of conspiracy to commit first-degree murder after his two alleged coconspirators had previously been acquitted of conspiracy at separate trials. The court of appeals rejected the defendant’s challenge to his conviction for conspiracy, holding that his conviction subsequent to the acquittals of his alleged coconspirators did not violate the rule of consistency. We affirm the judgment of the court of appeals and hold that the rule of consistency is not applicable to situations where all alleged coconspirators are not tried in the same proceeding.
I.
The defendant’s convictions stem from the slaying of seventeen-year-old Debra
Terhorst early in January of 1981. According to evidence presented at trial, Marquiz believed that the victim had stolen some property from his apartment, and he resolved to kill her. Marquiz enlisted the cooperation of Rudy Gallegos and Antonio Laroza in this endeavor. The three men induced the victim to accompany them to a location on Lookout Mountain, where they stabbed her several times and cut her throat, resulting in her death.
Shortly after the killing, Marquiz, Gallegos and Laroza were arrested and charged with first-degree murder and conspiracy to commit first-degree murder. §§ 18-3-102 and 18-2-201, 8B C.R.S. (1986). The cases against the three defendants were severed for trial. A jury found Gallegos guilty of first-degree murder but not guilty of conspiracy to commit first-degree murder. A separate jury acquitted Laroza of both the murder charge and the conspiracy charge. The trial of Marquiz did not begin until May 17, 1982, well after the trials of the other two defendants had been completed.
A jury found Marquiz guilty of both first-degree murder and conspiracy to commit first-degree murder. He was sentenced to concurrent terms of life imprisonment for first-degree murder and twelve years for conspiracy to commit first-degree murder. Marquiz appealed his judgment of conviction to the court of appeals, asserting several grounds for reversal. The court of appeals upheld the convictions, and we granted certiorari limited to the issue of whether Marquiz could properly be convicted of conspiracy after both Gallegos and Laroza had been acquitted of conspiracy charges in separate trials.
II.
The rule of consistency, simply stated, is that where all alleged coconspira-tors but one are acquitted of conspiracy, the remaining alleged coconspirator may not be convicted of conspiracy.
Bradley v. People,
157 Colo. 530, 403 P.2d 876 (1965);
Archuleta v. People,
149 Colo. 206, 368 P.2d 422 (1962).
See
Annot., 19 A.L.R. 4th 192, 198-204 (1983). When alleged cocon-spirators are tried in separate proceedings, however, the majority of courts that have considered the issue have held that the rule of consistency is inapplicable.
E.g., United States v. Sangmeister,
685 F.2d 1124 (9th Cir.1982);
United States v. Espinosa-Cerpa,
630 F.2d 328 (5th Cir.1980);
People v. Superior Court,
44 Cal.App.3d 494, 118 Cal.Rptr. 702 (1975);
Smith v. State,
250 Ga. 264, 297 S.E.2d 273 (1982);
Gardner v. State,
286 Md. 520, 408 A.2d 1317 (1979);
Commonwealth v. Cerveny,
387 Mass. 280, 439 N.E.2d 754 (1982);
People v. Anderson,
418 Mich. 31, 340 N.W.2d 634 (1983);
Platt v. State,
143 Neb. 131, 8 N.W.2d 849 (1943);
Commonwealth v. Byrd,
490 Pa. 544, 417 A.2d 173 (1980). A few courts have held, without extensive examination of the validity of the rationale for the rule in the context of separate trials, that the rule of consistency applies even when alleged coconspirators are tried in separate proceedings.

Casper v. Wisconsin,
47 Wis. 535, 2 N.W. 1117 (1879). We adopt the position of the majority of jurisdictions and hold that the rule of consistency is inapplicable where all alleged coconspirators are not tried in the same proceeding.
The rule of consistency has its origins in a time when all alleged coconspirators were routinely charged in the same proceeding.
See Platt v. State,
8 N.W.2d at 854;
Commonwealth v. Byrd,
417 A.2d at 177. In such cases the evidence against the defendants commonly would be identical and the
composition of the jury would be the same as to each defendant.
Were the jury to convict one defendant of conspiracy while acquitting the others “[t]he effect analytically [would be] that the fact-finder in such cases found simultaneously that ‘an agreement between two or more persons’ existed and that it did not exist with regard to the same alleged conspirators.”
People v. Anderson,
340 N.W.2d at 635.
See also Archuleta v. People,
149 Colo, at 211-12, 368 P.2d at 425. The rule of consistency therefore serves as a check upon the jury in two ways:
First, it insures that the jury will adhere to the conspiracy requirement of-the concurrence of at least two guilty minds; and second, it prevents the jury from weighing the same pieces of evidence differently in regard to each of the alleged conspirators.
People v. Superior Court,
118 Cal.Rptr. at 704;
cf. People v. Coca,
185 Colo. 10, 13, 521 P.2d 781, 783 (1974) (“A jury will not be permitted to believe the evidence for the purpose of the conspiracy and disbelieve it for the purpose of the substantive crime.”).

The rule of consistency has its origins in a time when all alleged coconspirators were routinely charged in the same proceeding.
See Platt v. State,

When alleged coconspirators are tried in separate proceedings, however, the reasons for the rule lose much if not all of their force.
There is no inherent inconsistency when different juries return different verdicts in separate trials, because the acquittal of one of the conspirators “ ‘could [result] from a multiplicity of factors completely unrelated to the actual existence of a conspiracy.’ ”
Commonwealth v. Byrd,
417 A.2d at 177 (quoting
United States v. Strother,
458 F.2d 424, 426 (5th Cir.),
cert. denied,
409 U.S. 1011, 93 S.Ct. 456, 34 L.Ed.2d 305 (1972)).
See also People v. Anderson,
340 N.W.2d at 636;
Platt v. State,
8 N.W.2d at 855. The evidence presented to the juries and the manner in which that evidence is presented may be significantly different and certainly will never be identical. Certain witnesses or other evidence may be available for one trial and not the other, the prosecution may not present all of the available evidence in each trial, new evidence may be discovered between trials, and the prosecution may not present its case as effectively in one trial as it does in the other.
Smith v. State,
297 S.E.2d at 274;
Platt v. Nebraska,
8 N.W.2d at 855;
Commonwealth v. Byrd,
417 A.2d at 177. In some instances, evidence may be admissible at the trial of one defendant but not at that of another.
Cf Standefer v. United States,
447 U.S. 10, 24-25, 100 S.Ct. 1999, 2008, 64 L.Ed.2d 689 (1980) (rejecting the applicability of the doctrine of nonmu-tual collateral estoppel to criminal prosecutions under federal law).
Different verdicts may also result simply from the different compositions of the juries. Separate juries may reasonably take different views of the same evidence. “Moreover, the jury may assume the power to acquit out of compassion or prejudice, and the prosecution is then powerless to seek a judgment notwithstanding the verdict or a new trial on the ground that the verdict is against the weight of the evidence.”
Commonwealth v. Cerveny,
439 N.E.2d at 757. Public policy dictates that we guard against compounding the effect
of a possibly erroneous or irrational acquittal. “ ‘Because there may have been a miscarriage of justice as to one joint offender is no reason why there should also be a miscarriage of justice as to the other joint offender.’ ”
Roberts v. People,
103 Colo. 250, 261, 87 P.2d 251, 257 (1938) (upholding conviction as accessory notwithstanding prior acquittal of principal, and quoting
Woody v. State,
10 Okla.Cr. 322, 136 P. 430, 432 (1913)).
The value of the rule of consistency as a check upon the jury also disappears in the context of separate trials.
Application of the consistency rule in this situation neither insures that the two juries understand the crime of conspiracy nor that they evaluated the facts of the case consistently in regard to each conspirator.
People v. Superior Court,
118 Cal.Rptr. at 705.
We conclude that the policies sought to be furthered by the rule of consistency are not served by application of the rule to situations in which all alleged coconspira-tors are not tried in the same proceeding.
The judgment of the court of appeals is affirmed.
