Cited. 217 C. 313.
Cited. 4 CA 608. Subdiv. (3): Protection of statute not invoked unless repair requested is necessary to maintain premises in a fit and habitable state. 16 CA 444. Cited. 32 CA 133; 45 CA 46. Sec. 47a-20a contains four exclusive grounds by which a landlord may rebut a presumption of retaliation under this section and because landlord did not prove at least one of those four grounds, he did not rebut the presumption of retaliation under this section. 91 CA 142. Language does not confer a private cause of action. 98 CA 147.
Cited. 35 CS 233. Retaliatory eviction defense is not a right given to tenants, rather a limitation upon remedies of landlord intended to protect tenant who had complained of housing code violation; tenant's request to landlord to unclog bathtub drain does not constitute a repair sufficient to raise the presumption of retaliatory defense; under Subdiv. (3), “repairs” means repairs of substantial code violations; repairs required to conform a dwelling unit to basic structural, mechanical and housing code regulations are the types contemplated to raise presumption of retaliatory defense; establishment of prima facie case by tenant gives rise to presumption of retaliatory action by landlord; prima facie case results when tenant has produced sufficient evidence to bring himself within one or more of the specified acts; presumption of retaliatory action is rebuttable; to rebut, landlord is required to establish legitimate interest in the eviction; landlord has burden of producing substantial countervailing evidence and of proving facts which fairly put in issue the presumed fact; Subdiv. (1) contains language nearly identical to that of Sec. 47a-33; Subdiv. (1) and three others in section are intended to trigger defense of retaliatory action. Id., 261.
