Mo. R. Crim. P. 31.02
Committee Note - 1980
Paragraph (a) is substantially the same as prior Rule 29.01(a) except for the second sentence which has been changed as follows: 'If any person charged with an offense, the conviction of which would probably result in confinement, shall be without counsel upon his first appearance before a judge, it shall be the duty of the court to advise him of his right to counsel, and of the willingness of the court to appoint counsel to represent him if he is unable to employ counsel.'
Paragraph (b) is substantially the same as prior Rule 29.01(b).
The source of paragraph (c) is prior Rule 29.01(c) and (d) but it is broadened to include situations where a defendant is sentenced to confinement after conviction of a misdemeanor.
