delivered the opinion of the Court.
We hold that in a criminal prosecution by the State of Maryland the constitutional rights to due process of law 1 are *621 not violated by placing upon the defendant the burden of proving by a preponderance of the evidence his assertion that a witness offered against him is an accomplice. 2

Foster Elwood Bennett was convicted in the Circuit Court for Montgomery County of robbery with a deadly weapon and the use of a handgun in the commission of a felony. He was sentenced to concurrent terms of imprisonment of eight years and five years, respectively, to begin at the expiration of a sentence he was then serving. The Court of Special Appeals affirmed the judgments on direct appeal. Bennett v. State, No. 587, September Term, 1977, decided 27 December 1977, unreported. At trial, the judge in considering whether a State’s witness was an accomplice should be submitted to the jury for determination, 3 said: “I think the law is that the burden is on the defendant to prove that a witness was an accomplice by a fair preponderance of affirmative evidence.” He did not believe that Bennett had so met the burden with regard to a witness, Leonard Fritz, as to exclude the submission of the matter to the jury. In affirming the judgments, The Court of Special Appeals stated flatly: “The burden of showing that Fritz was an accomplice was on [Bennett].” We granted Bennett’s petition for the issuance of *622 a writ of certiorari. The sole question presented was: “Did the Court of Special Appeals err in holding that [Bennett] had the burden of proving that Leonard Fritz was an accomplice?”

Whether the State’s witness was an accomplice is significant because of the role an accomplice plays in a .criminal prosecution in Maryland. A conviction may not rest on the uncorroborated testimony of an accomplice.

Brown v. State,

Bennett contends that “placing on a defendant the burden of proving that a witness is an accomplice is a violation of due process.” He looks to
In re Winship,
In
Winship,
the Court declared that the “Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged.”
“In sum, under the Federal Constitution, as well as the law of Maryland, the burden is on the State to prove all elements of the alleged crime and to do so beyond a reasonable doubt; hence, the defendant does not have to establish his alibi, not even by a minimal standard of proof.” Id.
The rationale of our holding in
Grady
is found in our acceptance “as a succinct and accurate expression of the law of this State,”
“We think the sound view to be that an alibi is not an affirmative defense, placing any burden upon a defendant beyond the self-evident one of attempting to erode the State’s proof to a point where it no longer convinces the fact finder beyond a reasonable doubt. Proof of an alibi, like any other defense testimony, is simply a means of controverting the State’s effort to establish criminal agency.” Id. at 459.
Patterson
made clear that
Mullaney
went no further than to hold that “a State must prove every ingredient of an offense beyond a reasonable doubt, and that it may not shift the burden of proof to the defendant by presuming that ingredient upon proof of the other elements of the offense----Such shifting of the burden of persuasion with respect to a fact which the State deems so important that it must be either proved or presumed is impermissible under the
*626
Due Process Clause.”
Both
Grady
and
State v. Evans
are in complete accord with this. In
Grady,
as we have indicated, we concluded that under the teachings of the Supreme Court “the burden is on the State to prove all elements of the alleged crime and to do so beyond a reasonable doubt.”
“Of course, nothing in Mullaney^&c se precludes the use of traditional presumptions, or logical inferences arising from established facts; what Mullaney precludes is the use of such presumptions or inferences only when they operate, ultimately, to relieve the State of its burden of persuasion in a criminal case, i.e., its burden of proving beyond a reasonable doubt all the facts necessary to constitute the offense when the issue of their existence becomes an issue in the case. State v. Hankerson,288 N. C. 632 ,220 S.E.2d 575 (1975).”278 Md. at 207 .
The answer to the question presented to us is obvious. Proof by a defendant that a State’s witness is an accomplice involves no shifting of the burden to him to disprove any fact essential to the offenses charged since whether or not the witness was an accomplice bears no direct relationship to any element of robbery with a deadly weapon or the use of a handgun in the commission of a felony. That is, the fact that
*627
Fritz was an accomplice
vel non
was not a fact necessary to constitute the crimes with which Bennett was charged. It was not even an affirmative defense or an exculpatory or mitigating circumstance affecting the degree of culpability or the severity of punishment. Nothing was presumed or implied against Bennett. Whether Fritz was an accomplice went only to Fritz’s credibility. If he were an accomplice, his credibility is so thought in this State to be in question as to require that the evidence adduced through his testimony be corroborated.
11
We believe it to be fundamental that a party who seeks to attack the credibility of a witness has the burden of going forward. This is indicated by the general principle that a party ordinarily may not sustain the credibility of his own witness absent an attack upon credibility by the other side.
City of Baltimore v. Zell,
As placing the burden on a defendant to prove that a witness against him is an accomplice has no constitutional proscriptions and is pursuant to the existing rule of this State, it necessarily follows that the Court of Special Appeals did not err in holding that Bennett had the burden of proving that the State’s witness, Fritz, was an accomplice. The judgment of the Court of Special Appeals is

U.S. Const., amend. XIV, § 1. “[N]o man ought to be taken or imprisoned or disseized of his freehold, liberties or privileges, or outlawed, or exiled, or, in any manner, destroyed, or deprived of his life, liberty or property, but by the judgment of his peers, or by the Law of the land.” Declaration of Rights, Md. Const., art. 23. It is firmly established that art. 23 of the Maryland Declaration of Rights is in harmony with the Fourteenth Amendment to the Federal Constitution, and that the term “due process of law,” as used in that amendment, is synonymous with the phrase “Law of the land” as used in art. 23. Raymond v. State ex rel. Szydlouski,
We note that Acts 1977, ch. 681, proposes that art. 24, “Slavery,” be repealed and that art. 23 be designated art. 24. A new art. 23 concerning juries in criminal cases being judges of law as well as of fact, as now appears in Md. Const., art. XV, §§ 5, 6 would become art. 23. The amendments will be voted upon at the general election to be held in November, 1978.

. “When the evidence relating to whether or not a witness is an accomplice is capable of being determined either way and justifies different inferences in respect thereto, the question is for the determination of the trier of fact and in a jury case should be submitted to the jury with proper instructions.” Burley v.

. This rule in Maryland was indicated in Lanasa v. State,
. The statement in the 1940 edition of Wigmore is iterated without change in 7 Wigmore, Evidence § 2060 (e) (Chadbourn rev. 1978). Sections 2056 et seq. of the new edition contain a most comprehensive discussion of the uncorroborated accomplice.

Mullaney
did not expressly overrule Leland v. Oregon,
. The Court refused to “disturb the balance struck in previous cases holding that the Due Process Clause requires the prosecution to prove beyond a reasonable doubt all of the elements included in the definition of the offense of which the defendant is charged.” Patterson v. New York,
. “Not much in the way of evidence corroborative of the accomplice’s testimony has been required by our cases. We have, however, consistently held the view that while the corroborative evidence need not be sufficient in itself to convict, it must relate to material facts tending either (1) to identify the accused with the perpetrators of the crime or (2) to show the participation of the accused in the crime itself.” Brown v. State,
