Whenever a party to any proceeding in a district court makes and
files a timely and sufficient affidavit that the judge before whom
the matter is pending has a personal bias or prejudice either
against him or in favor of any adverse party, such judge shall
proceed no further therein, but another judge shall be assigned to
hear such proceeding.
The affidavit shall state the facts and the reasons for the
belief that bias or prejudice exists, and shall be filed not less
than ten days before the beginning of the term at which the
proceeding is to be heard, or good cause shall be shown for failure
to file it within such time. A party may file only one such
affidavit in any case. It shall be accompanied by a certificate of
counsel of record stating that it is made in good faith.
