All parties, except individuals appearing in their own behalf, shall be represented by attorneys-at-law, who are duly admitted and enrolled to practice before the Court of Appeals of this State when the Commission is performing a quasi-judicial function as distinguished from a legislative, executive, or a ministerial function. A nonresident attorney may not be allowed to enter his appearance in a case before the Commission except upon motion, which will not ordinarily be granted unless some attorney with a full-time office in this State is associated with him or her in the matter. Reports of all accidents required to be filed with the Commission shall be made in writing within 30 days after its happening, or as prescribed by order of the Commission duly served. On receiving a petition, application, or complaint in writing, the Commission will refer it to the Secretary for examination. If it is found to conform to these regulations and all statutory provisions, the Secretary shall report that fact to the Commission. If it does not so conform, he shall advise the applicant of the defects, which may then be corrected. When the papers and any accompanying exhibits are in proper form, a time and place for a hearing on them may be appointed. The Commission will, in each case, direct what notice of a hearing shall be given, whether by publication or otherwise, and to whom. The applicant shall furnish at its expense, for the use of the Commission in determining the application, the originals of all books, papers, and documents which it may require, or certified or verified copies of them. The failure to do so shall be ground for refusing the application. All petitions, complaints, applications, answers, briefs, and other papers filed with the Commission, shall be printed or typewritten, whenever practicable, upon sheets not more than 11 inches long and 8-1/2 inches wide. An application by a corporation, firm, or person for an extension of the time within which a report is or may be required to be filed with the Commission, shall be in writing, filed before the expiration of the period, the extension of which is deemed necessary, and shall state in detail: What, if any, effort has been made by the applicant to prepare the report; Any facts tending to show why the report cannot be made and filed within the time prescribed; Any other facts which may make an extension of time necessary or proper; and The further period of time deemed necessary by the applicant within which to make and file the report.
