A notice given under the provisions of section 72-701 or section 72-448, Idaho Code, shall not be held invalid or insufficient by reason of any inaccuracy in stating the time, place, nature or cause of the injury, or disease, or otherwise, unless it is shown by the employer that he was in fact prejudiced thereby. Want of notice or delay in giving notice shall not be a bar to proceedings under this law if it is shown that the employer, his agent or representative had knowledge of the injury or occupational disease or that the employer has not been prejudiced by such delay or want of notice.
