to force victim to have sexual intercourse with him and intended to compel sexual intercourse by use of force or the threat
of use of force. 75 CA 447. Because the necessary elements of this section and Sec. 53-21 are distinct, court's respective
findings of not guilty and guilty of these distinct crimes was not legally inconsistent. 78 CA 25. Trial court's finding that
the state had proven, by a preponderance of the evidence, that defendant had committed sexual assault in the first degree
and thereby violated his probation was not clearly erroneous and was supported by the evidence. 108 CA 250.

Id., 756; 46 CA 810. Conviction of both sexual assault and unlawful restraint is not double jeopardy. 47 CA 117. Trial
court did not abuse its discretion in commenting on testimony of state's expert witness concerning inconsistencies in results
of victim's rape kit tests, that court having also instructed jury to base findings on recollection of all evidence presented;
defendant's challenge to other aspects of instructions on scientific evidence were not properly preserved for appellate
review. Trial court properly admitted victim's written statement to police as constancy of accusation evidence; defendant
failed to establish that court abused its discretion or that he was prejudiced by admission of that evidence, and his claim
that victim's statement is admissible only if tape recorded was incorrect. 48 CA 135. Subdiv. (1): Trier of fact reasonably
could have concluded beyond a reasonable doubt that defendant compelled victim to engage in sexual intercourse by use
of force. 52 CA 466. Subdiv. (1): Defendant could not succeed in argument that the evidence did not support a guilty
verdict under section; jury could reasonably have concluded that the facts and inferences established guilt beyond reasonable
doubt. 55 CA 412. Evidence was sufficient for jury to find defendant guilty beyond a reasonable doubt. 57 CA 736. Statute
is not unconstitutionally vague as applied to facts of the case. 58 CA 585. Evidence was sufficient to establish guilt beyond
a reasonable doubt. 75 CA 201. Subdiv. (1): Sexual assault in the second degree was not a lesser offense included within
sexual assault in the first degree because it would be possible to commit the latter offense in the manner described in the
information and bill of particulars without committing the former offense. 99 CA 251.
