"Entry of appearance" --
"General." A representative of a party or intervenor shall enter an appearance by signing the first
document filed on behalf of the party or intervenor in accordance with paragraph (a)(2) of this section, or thereafter by filing an entry of
appearance in accordance with paragraph (a)(3) of this section.
"Appearance in first document or pleading." If the first document filed on behalf of a party or
intervenor is signed by a representative, he shall be recognized as representing that party. No separate entry of appearance by him is necessary,
provided the document contains the information required by 2200.6.
"Subsequent appearance." Where a representative has not previously appeared on behalf of a party or
intervenor, he shall file an entry of appearance with the Executive Secretary, or Judge if the case has been assigned. The entry of appearance shall
be signed by the representative and contain the information required by 2200.6.
"Withdrawal of counsel." Any counsel or representative or record desiring to withdraw his appearance,
or any party desiring to withdraw the appearance of counsel or representative of record for him, must file a motion with the Commission or Judge
requesting leave therefor, and showing that prior notice of the motion has been given by him to his client or counsel or representative, as the case
may be. The motion of counsel to withdraw may, in the discretion of the Commission or Judge, be denied where it is necessary to avoid undue delay or
prejudice to the rights of a party or intervenor.
