Defendant appeals from his conviction for driving while intoxicated in violation of Section 577.010, RSMo 1986. We affirm.
Officer Charles Marvin of the St. Louis Police Department was on patrol at 3:00 a.m. on February 6, 1987. He saw a 1977 blue Malibu stop momentarily and then proceed through a red light in the 2900 block of South Jefferson. At the next intersection, the driver repeated the same traffic violation. The officer turned on his red lights and pulled the vehicle over to the side of the road. The defendant alighted as did a passenger. Concurrently, a second police officer arrived on the scene. Both officers testified that the defendant’s eyes were red, watery and bloodshot; that his speech was slow and slurred; and that his breath had a strong alcohol odor. The defendant was arrested and given the appropriate Miranda warnings. He was advised that he had the right to submit to or refuse a breathalyzer test, but that if he refused, the Director of Revenue could revoke his driver’s license for one year. Defendant refused to submit to the breathalyzer test but volunteered to take a field sobriety test. In this test, defendant managed to recite the alphabet; however, his speech was slow and slurred. He failed to walk a straight line, maintain his balance on either foot, or to touch his nose with either index finger when his eyes were closed. It was the opinion of both officers that the defendant was intoxicated.
On the rear seat of defendant’s vehicle, the officers discovered a bag containing eight unopened cans of cold beer. No empty cans were found in the vehicle.
Defendant presented the testimony of the physician who had treated him since June, 1987. The physician testified that the defendant suffered from pragmatic chronic degenerative joint disease (a type of arthritis) of the knees which would have caused severe pain and difficulty in performing two of the field sobriety tests, standing on one leg and walking a straight line. The physician testified that he had not treated the defendant at the time of or before his arrest nor did he know if the defendant was being treated with prescription drugs at that time. In addition, he testified that defendant’s arthritic condition would not have caused his eyes to appear red, watery and bloodshot, nor would it have caused him difficulty in performing the finger-to-nose test. Defendant’s physician had never observed the defendant’s speech to be slurred.
The jury convicted the defendant, and the court sentenced him as a prior offender to six months imprisonment.
Initially, we will address defendant’s second point because much of our later analysis hinges on its resolution. The relevant statute in effect at the time of the defendant’s arrest was Section 577.041.1, RSMo 1986, which begins:
If a person under arrest refuses upon the request of the arresting officer to submit to a chemical test, which request shall include the reasons of the officer for requesting the person to submit to a test and which also shall inform the person that his license may be revoked upon *231 his refusal to take the test, then none shall be given.
After the defendant’s arrest but before the date of this trial, the statute was amended to read:
If a person under arrest refuses upon the request of the arresting officer to submit to any test allowed under section 577.020, then none shall be given and evidence of the refusal shall be admissible in a proceeding under section 577.010 or 577.012. The request of the arresting officer shall include the reasons of the officer for requesting the person to submit to a test and also shall inform the person that evidence of his refusal to take the test may be used against him and that his license may be revoked upon his refusal to take the test.
Section 577.041.1, RSMo Supp.1987 (effective Sept. 28, 1987).
Defendant asserts that the trial court erroneously applied the amended statute rather than the statute that was in effect at the time of the defendant’s arrest, thereby, violating the prohibition against ex post facto laws.
It is appropriate to begin with a brief summary of the law with regard to the ex post facto impact of changes in evidentiary rules. Laws which change the elements or facts
necessary
to establish guilt are substantive in nature and as such are subject to ex post facto prohibition; whereas, mere procedural changes are not subject to such prohibition.
Miller v. Florida,
— U.S. -,-,
The leading Supreme Court case is
Beazell v. Ohio,
Later cases from our sister states shed more light on the application of the ex post facto prohibition. The distinction in all the cases seems to be whether the statute in question changed the quantum or amount of evidence required for conviction. Therefore, the repeal of a statute that precluded
*232
conviction of an accused solely on the uncorroborated testimony of an accomplice and the subsequent passage of a statute permitting the uncorroborated testimony of an accomplice to be sufficient evidence upon which to base a conviction violated the constitutional prohibition against ex post facto laws.
State v. Schreuder,
Defendant, in the case before us, contends that the change in the evidentiary rule “penalized an act which could not have been used against him when done.” Defendant was not penalized in this trial for his refusal to submit to breathalyzer testing; his penalty was assessed for driving under the influence of alcohol. One fact that may have been considered by the jury in determining the defendant’s guilt was his refusal to be tested; however, the evidence of refusal was not necessary or conclusive in the jury’s determination of guilt, and the change did not affect the amount of evidence required to convict the defendant. Missouri law does not prohibit the retrospective application of a law or rule that deals only with procedure or remedies.
State v. Kummer,
Defendant argues that the change at issue affects a substantial right, namely, his right to refuse to submit to breathalyzer testing. While defendant correctly points to his statutory right to refuse testing, he is not constitutionally protected from the adverse consequences of his refusal. The Supreme Court examined this subject in
South Dakota v. Neville,
The
Neville
Court first considered whether the refusal to submit to the test was protected by the fifth amendment’s privilege against self-incrimination, holding: “[A] refusal to take a blood-alcohol test, after a police officer has lawfully re
*233
quested it, is not an act coerced by the officer, and thus is not protected by the privilege against self-incrimination.”
Id.
at 565,
The Court in
Neville
further considered a due process claim and held that the admission of evidence of a refusal following the warning that refusal may result in loss of driving privileges for one year “comported with the fundamental fairness required by due process.”
Id.
at 566,
The amendment of former Section 577.-041, RSMo 1986, initiates a change which is procedural in nature. The application of the amended statute does not violate any of the defendant’s constitutional rights; therefore, the trial court did not err. 1
Defendant objected to the prosecution argument that his refusal to take a breathalyzer test was evidence of his guilt. The basis for his objection was that his statutory right to refuse made it fundamentally unfair and, therefore, a violation of due process to use that refusal against him and that the argument amounted to a comment on defendant’s silence while under arrest. He relies on
City of St. Joseph v. Johnson,
Defendant urges us to find that the trial court erred by refusing Instruction “A,” a non-MAI instruction submitted by the defendant. It read:
Under the law, a defendant has the right to refuse to take a breathalyzer test. No presumption of guilt may be raised, and no inference of any kind may be drawn from the fact that the defendant did not take a breathalyzer test.
The reasons for offering this instruction have been rejected in our discussion of defendant’s first two points on appeal. “When a requested instruction is incorrect, refusal to give it is not error.”
State v. Garrette,
Defendant’s final point alleges that the trial court erred by refusing to permit the defendant to introduce exculpatory portions of his statements to the police because they were admissible under either the res gestae exception or the entire conversation exception to the hearsay rule. In defendant’s offer of proof, the police officer revealed that the defendant told him that he had drunk two beers earlier but was not drunk. He had also stated that the beer found on the rear seat of the car belonged to the passenger. These statements constituted self-serving hearsay and, when offered by the defendant, were inadmissible unless they came within a recognized exception to the hearsay rule.
Defendant contends that the statements are admissible under the
res gestae
exception; however, the statement must be a spontaneous statement produced by the event itself to come within this exception.
State v. Hook,
Defendant also contends that the statements came under the entire conversation exception to the hearsay rule. To come within this exception, the statements that the defendant sought to introduce must be reasonably related to and explanatory of the statements already admitted.
State v. Hodges,
The direct examination statements that were in evidence were the defendant’s negative answers to police questions concerning whether he was under treatment by a physician or taking any medication at the time of his arrest. Further statements about the amount of beer the defendant had consumed, ownership of the beer found in the vehicle, and defendant’s opinion with regard to his state of intoxication were unrelated to his statements concerning his medical history. They did not tend to explain, contradict, or qualify the statements already in evidence; thus, they were not within the entire conversation exception.
The judgment is affirmed.
Notes
. Assuming that the statute had not been amended, our result would have been the same. This court held in a case under the former statute, Section 577.041, RSMo 1986, that although it was error to admit evidence of the defendant’s refusal to submit to breathalyzer testing, the error was harmless because the other evidence of guilt was strong.
