That CCB can be sued in court by her neighbour for trespass and nuisance. Her neighbour should be able to get an injunction against her. If she doesn’t comply she should be charged with contempt of court and go to jail.
This is supported by the rule in Rylands v Fletcher, which is good law in Singapore. From Wikipedia:
https://en.wikipedia.org/wiki/Rylands_v_Fletcher
Rylands v Fletcher [1868] UKHL 1 was a decision by the
House of Lords which established a new area of
English tort law. Rylands employed contractors to build a reservoir, playing no active role in its construction. When the contractors discovered a series of old coal shafts improperly filled with debris, they chose to continue work rather than properly blocking them up. The result was that on 11 December 1860, shortly after being filled for the first time, Rylands' reservoir burst and flooded a neighbouring mine, run by Fletcher, causing £937 worth of damage, equivalent to £110,653.84
[1] in 2018 terms. Fletcher brought a claim under
negligence against Rylands, through which the case eventually went to the
Exchequer of Pleas.
[2] The majority ruled in favour of Rylands.
Bramwell B, however, dissenting, argued that
the claimant had the right to enjoy his land free of interference from water [asterix: or poisonous second hand smoke] and that as a result the defendant was guilty of trespass and the commissioning of a nuisance. Bramwell's argument was affirmed, both by the Court of Exchequer Chamber and the House of Lords, leading to the development of the "Rule in Rylands v Fletcher"; that "the person who for his own purposes brings on his lands and collects and keeps there anything likely to do mischief if it escapes [asterix: that CCB woman smoker let her disgusting second hand smoke escaped from her house to other people’s houses didn’t she, that bastard poison inhaler!!!!], must keep it in at his peril, and, if he does not do so, is prima facie answerable for all the damage which is the natural consequence of its escape".[3] No right "to enjoy property" exists in UK black letter law, and it is this decision upon which stare decisisis built in the area.
By the way, I am not a lawyer. I just have a photographic memory that’s all (
