Code Civ. Proc., § 1211.5

At all stages of all proceedings, the affidavit or statement of facts, as the case may be, required by Section 1211 shall be construed, amended, and reviewed according to the followings rules:

(a) If no objection is made to the sufficiency of such affidavit or statement during the hearing on the charges contained therein, jurisdiction of the subject matter shall not depend on the averments of such affidavit or statement, but may be established by the facts found by the trial court to have been proved at such hearing, and the court shall cause the affidavit or statement to be amended to conform to proof.

(b) The court may order or permit amendment of such affidavit or statement for any defect or insufficiency at any stage of the proceedings, and the trial of the person accused of contempt shall continue as if the affidavit or statement had been originally filed as amended, unless substantial rights of such person accused would be prejudiced thereby, in which event a reasonable postponement, not longer than the ends of justice require, may be granted.

(c) No such affidavit or statement is insufficient, nor can the trial, order, judgment, or other proceeding thereon be affected by reason of any defect or imperfection in matter of form which does not prejudice a substantial right of the person accused on the merits. No order or judgment of conviction of contempt shall be set aside, nor new trial granted, for any error as to any matter of pleading in such affidavit or statement, unless, after an examination of the entire cause, including the evidence, the court shall be of the opinion that the error complained of has resulted in a miscarriage of justice.
