If it appears to a court that a person requesting the appointment of counsel satisfies the requirements of this chapter, the court shall order the appropriate public defender to represent the person at all further stages of the proceeding through appeal, if any. For a person appealing from a conviction, or a person pursuing a postconviction proceeding and who has not already had a direct appeal of the conviction, according to the standards of sections 611.14 and 611.25, subdivision 1, paragraph (a), clause (2), the state public defender shall be appointed. For a person covered by section 611.14, clause (1), a district public defender shall be appointed to represent that person. If (a) conflicting interests exist, (b) the district public defender for any other reason is unable to act, or (c) the interests of justice require, the state public defender may be ordered to represent a person. When the state public defender is directed by a court to represent a defendant or other person, the state public defender may assign the representation to any district public defender. If at any stage of the proceedings, including an appeal, the court finds that the defendant is financially unable to pay counsel whom the defendant had retained, the court may appoint the appropriate public defender to represent the defendant, as provided in this section. Prior to any court appearance, a public defender may represent a person accused of violating the law, who appears to be financially unable to obtain counsel, and shall continue to represent the person unless it is subsequently determined that the person is financially able to obtain counsel. The representation may be made available at the discretion of the public defender, upon the request of the person or someone on the person's behalf. Any law enforcement officer may notify the public defender of the arrest of any such person.
