(1952) The "matter referred to in his examination in chief" means the things he testifies about. If defendant in chief in a general way refers to a subject, he may be examined in detail as to that subject. State v. Christian (Mo.), 245 S.W.2d 895.
(1952) Where defendant ex-policeman testified as to his work as policeman and his training, cross-examination as to whether he got in trouble during training was improper but general objection not sufficient to preserve objection. Specific objection on ground no conviction shown made at close of cross-examination also not sufficient to preserve same. State v. Slaten (Mo.), 252 S.W.2d 330.
(1953) Where defendants on direct examination denied stealing corn, they could be cross-examined as to their signatures to conflicting statements as to crime made in prosecuting attorney's office, even though statements were not introduced and particularly is this so where stenographer testified without objection from her notes as to matters contained in such statements. State v. Kaufman (Mo.), 254 S.W.2d 640.
(1953) Where defendant in criminal case offered himself as witness and, on cross-examination for purpose of impeachment, gave false answers as to his prior convictions of crime, he was guilty of perjury. State v. Swisher, 364 Mo. 157, 260 S.W.2d 6.
(1956) Where officer was called by defense in robbery prosecution to impeach state's witnesses, his cross-examination, for the purpose of showing defendant had been arrested on another charge, held error. State v. Ingram (Mo.), 286 S.W.2d 733.
(1957) Wife, testifying voluntarily, held competent witness against her husband in prosecution for acts constituting crime of personal violence against her child. State v. Kollenborn (Mo.), 304 S.W.2d 855.
(1958) In prosecution upon charge of performing an abortion where defendant's testimony on direct examination was in effect a general denial, cross-examination of defendant in regard to the right of access to and control of the house in which state's evidence tended to show the abortion took place was proper. State v. Scown (Mo.), 312 S.W.2d 782.
(1958) Under common law court did not err in permitting wife to testify on behalf of state in prosecution of defendant for statutory rape of his eight-year-old daughter as to what she found when she returned home and found defendant and the child. State v. Greer (Mo.), 313 S.W.2d 711.
(1959) Where defendant in criminal case took stand, cross-examination of him with respect to his former convictions was a proper method of impeachment. State v. Reece (Mo.), 324 S.W.2d 656.
(1959) Where husband on trial for murder testified to an alleged confidential communication between him and his wife and by such testimony attempted to blacken her reputation for his own advantage, he was held to have waived her incompetency and her testimony as to the communication and as to the commission of the crime was properly admitted in rebuttal. State v. Bledsoe (Mo.), 325 S.W.2d 762.
(1959) Where defendant took stand as witness, his cross-examination as to prior convictions, including misdemeanor convictions, held proper. State v. Ivory (Mo.), 327 S.W.2d 870.
(1960) Where defendant makes sweeping denial of commission of crime in testimony on his own behalf, he is liable to cross-examination, contradiction and impeachment as any other witness. State v. Beishir (Mo.), 332 S.W.2d 898.
(1960) Spouse of individual charged with crime is not precluded from testifying against coindictee of spouse where such coindictee is separately tried. State v. Gyngard (Mo.), 333 S.W.2d 73.
(1960) Where defendant in criminal case takes stand as witness in his own behalf he may be cross-examined as any other witness with respect to former convictions upon the issue of his credibility as a witness. State v. Morton (Mo.), 338 S.W.2d 858.
(1961) After asking a series of prejudicial and improper questions of defendant which related to matters beyond scope of direct examination objections to which were sustained by the court, comment by prosecuting attorney that "if the court please, we have got the right to put on some testimony from this witness" prejudiced the rights of defendant and was not relieved by direction of court to disregard the statement. State v. Sarten (Mo.), 344 S.W.2d 1.
(1962) Where defendant, in prosecution for subornation of perjury, testified as to his truthfulness it was proper for state to cross-examine defendant regarding prior jail sentence and fine for contempt of court for false swearing. State v. Baldwin (Mo.), 358 S.W.2d 18.
(1962) Admission in evidence of photograph of defendant taken after arrest showing defendant's hair to be long where at time of trial he had a crew cut and identity of defendant was disputed, upheld against contention it compelled defendant to testify against himself. State v. Sanders (Mo.), 358 S.W.2d 45.
(1962) Defendant in robbery prosecution, by taking the stand and testifying in his own defense, waived the error, if any, in requiring him to be sworn before exhibiting himself before jury in hat, sweater, gloves and stocking mask worn by robber. State v. Byrd (Mo.), 360 S.W.2d 614.

(1970) The right of an accused to testify in his own behalf is a statutory and not a constitutional right. State v. Hutchinson (Mo.), 458 S.W.2d 553.
(1974) Cross-examination as to whether defendant changed coats with a codefendant before a police lineup was proper since on direct examination the denial of guilt by the defendant was broad enough to allow evidence of consciousness of guilt or a disposition to conceal the alleged crime as indicated by the changing of coats. State v. Kirk (A.), 510 S.W.2d 196.
(1976) When defendant testified that he did not shoot victim but that third person did, evidence that defendant attempted to suborn perjury in support of his testimony constitutes direct contradiction of his examination in chief and is admissible to impeach him. State v. Moore (A.), 546 S.W.2d 10.
(1977) Held, a person may testify against his spouse, the privilege belongs to the witness and must be asserted by the witness. State v. Frazier (A.), 550 S.W.2d 590.
(1977) Where defendant testified on direct examination that he had never been "in trouble" except for one instance, cross-examination as to prior arrests was permissible. State v. Payton (A.), 559 S.W.2d 551.
