      Sec. 31-284. Basic rights and liabilities. Civil action to enjoin noncomplying 
employer from entering into employment contracts. Notice of availability of compensation. (a) An employer who complies with the requirements of subsection (b) of 
this section shall not be liable for any action for damages on account of personal injury 
sustained by an employee arising out of and in the course of his employment or on 
account of death resulting from personal injury so sustained, but an employer shall 
secure compensation for his employees as provided under this chapter, except that compensation shall not be paid when the personal injury has been caused by the wilful and 
serious misconduct of the injured employee or by his intoxication. All rights and claims 
between an employer who complies with the requirements of subsection (b) of this 
section and employees, or any representatives or dependents of such employees, arising 
out of personal injury or death sustained in the course of employment are abolished 
other than rights and claims given by this chapter, provided nothing in this section 
shall prohibit any employee from securing, by agreement with his employer, additional 
compensation from his employer for the injury or from enforcing any agreement for 
additional compensation.
      (b) Each employer who does not furnish to the chairman of the Workers' Compensation Commission satisfactory proof of his solvency and financial ability to pay directly 
to injured employees or other beneficiaries compensation provided by this chapter shall 
insure his full liability under this chapter, other than his liability for assessments pursuant 
to sections 31-345 and 31-354 in one of the following ways: (1) By filing with the 
Insurance Commissioner in form acceptable to him security guaranteeing the performance of the obligations of this chapter by the employer; or (2) by insuring his full liability 
under this part, exclusive of any liability resulting from the terms of section 31-284b, 
in any stock or mutual companies or associations that are or may be authorized to take 
such risks in this state; or (3) by any combination of the methods provided in subdivisions 
(1) and (2) of this subsection as he may choose, subject to the approval of the Insurance 
Commissioner. If the employer fails to comply with the requirements of this subsection, 
an employee may bring an action against such employer for damages on account of 
personal injury sustained by such employee arising out of and in the course of his employment or on account of death resulting from personal injury so sustained, except that 
there shall be no liability under this section to an individual on the part of the employer 
if such individual held himself out to the employer as an independent contractor and 
the employer, in good faith, relied on that representation as well as other indicia of such 
status and classified such individual as an independent contractor. In case of an alleged 
noncompliance with the provisions of this subsection, a certificate of noncompliance 
under oath, by the chairman of the Workers' Compensation Commission, shall constitute 
prima facie evidence of noncompliance.
      (c) Each employer who does not furnish to the chairman of the Workers' Compensation Commission satisfactory proof of his solvency and financial ability to pay directly 
to the State Treasurer the assessments required in sections 31-345 and 31-354 shall 
insure his full liability for the assessments in one of the following ways: (1) By filing 
with the Insurance Commissioner in form acceptable to him security guaranteeing the 
payment of the assessments by the employer; (2) by insuring his full liability for the 
assessments in any stock or mutual companies or associations that are or may be authorized to take such risks in this state; or (3) by any combination of the methods provided 
in subdivisions (1) and (2) of this subsection as he may choose, subject to the approval 
of the Insurance Commissioner. The payment of the assessments required under sections 
31-345 and 31-354 is a condition of doing business in this state and failure to pay the 
assessments, when due, shall result in the denial of the privilege of doing business in 
this state or to self-insure under subsections (b) and (c) of this section. If the liability 
for the assessments is insured, the insurance shall be by endorsement to a policy meeting 
all of the requirements of the Insurance Commissioner, or by a separate policy insuring 
the liability for the assessments, and otherwise meeting all of the requirements of the 
Insurance Commissioner. In the case of any employer who files acceptable security 
guaranteeing the liability for the assessments, failure to pay the assessments, when due, 
shall result in the denial of the privilege to self-insure under subsections (b) and (c) of 
this section.
      (d) Any employer to whom a certificate of self-insurance has been issued pursuant 
to this section who fails or is unable to pay any compensation mandated by the provisions 
of this chapter, thereby requiring payment from the Second Injury Fund pursuant to 
section 31-355, shall be prohibited from self-insuring his liability under this chapter for 
a period of ten years from the date of the payment. The employer shall be required during 
the ten-year period to insure his full liability under this part, exclusive of any liability 
resulting from the terms of section 31-284b, in any stock or mutual companies or associations that are or may be authorized to take such risks in this state. Failure to so insure 
his liability shall result in the denial of the privilege of doing business in this state.
      (e) Whenever an employer fails to comply with the requirements of subsection (b) 
of this section, the Attorney General may bring a civil action in the superior court for 
the judicial district of Hartford to enjoin the employer, until such time as he fully complies with such requirements, from entering into any contracts of employment as a result 
of which he will employ additional employees.
      (f) Each employer subject to the provisions of this chapter shall post, in a conspicuous place, a notice of the availability of compensation, in type of not less than ten-point 
boldface. The notice shall contain, at a minimum, the information required by regulations 
adopted pursuant to section 31-279.
