An aggrieved person authorized by law to request a fair hearing on a decision of the Commissioner of Social Services or the conservator of any such person on his behalf may make application for such hearing in writing over his signature to the commissioner and shall state in such application in simple language the reasons why he claims to be aggrieved. Such application shall be mailed to the commissioner within sixty days after the rendition of such decision. The commissioner shall thereupon hold a fair hearing within thirty days from receipt thereof and shall, at least ten days prior to the date of such hearing, mail a notice, giving the time and place thereof, to such aggrieved person, or if the application concerns a denial of or failure to provide emergency housing, the commissioner shall hold a fair hearing within four business days from receipt thereof, and shall make all reasonable efforts to provide notice of the time and place of the fair hearing to such aggrieved person at least one business day prior to said hearing. A reasonable period of continuance may be granted for good cause. The aggrieved person shall appear personally at the hearing, unless his physical or mental condition precludes appearing in person, and may be represented by an attorney or other authorized representative. A stenographic or mechanical record shall be made of each hearing, but need not be transcribed except (1) in the event of an appeal from the decision of the hearing officer or (2) if a copy is requested by the aggrieved person, in either of which cases it shall be furnished by the Commissioner of Social Services without charge. The Commissioner of Social Services and any person authorized by him to conduct any hearing under the provisions of this section shall have power to administer oaths and take testimony under oath relative to the matter of the hearing and may subpoena witnesses and require the production of records, papers and documents pertinent to such hearing. No witness under subpoena authorized to be issued by the provisions of this section shall be excused from testifying or from producing records, papers or documents on the ground that such testimony or the production of such records or other documentary evidence would tend to incriminate him, but such evidence or the records or papers so produced shall not be used in any criminal proceeding against him. If any person disobeys such process or, having appeared in obedience thereto, refuses to answer any pertinent question put to him by the commissioner or his authorized agent or to produce any records and papers pursuant thereto, the commissioner or his agent may apply to the superior court for the judicial district of Hartford or for the judicial district wherein the person resides, or to any judge of said court if the same is not in session, setting forth such disobedience to process or refusal to answer, and said court or such judge shall cite such person to appear before said court or such judge to answer such question or to produce such records and papers and, upon his refusal to do so, shall commit such person to a community correctional center until he testifies, but not for a longer period than sixty days. Notwithstanding the serving of the term of such commitment by any person, the commissioner or his agent may proceed with such inquiry and examination as if the witness had not previously been called upon to testify. Officers who serve subpoenas issued by the commissioner or under his authority and witnesses attending hearings conducted by him hereunder shall receive like fees and compensation as officers and witnesses in the courts of this state to be paid on vouchers of the commissioner on order of the Comptroller.
