A housewife ordered to be evicted from a public housing flat because her adopted son stashed heroin there is taking the Housing Authority to court after an authority tribunal rejected her appeal against the order. Lo Yuet-hing says she should not be punished for the crime of her adopted son, Luk Kam-wah, who hid 70 grams of heroin in a mahjong table in the flat. Luk was jailed in June 2000 for five years after pleading guilty to drug trafficking, Ms Lo's application to the High Court says. She is seeking leave to apply for a judicial review in the hope of overturning the Housing Authority's decision to terminate her tenancy. On May 25 last year, the authority served Ms Lo with a notice to quit by June 30 a flat in Lok Shing House, Tsz Lok Estate, Tsz Wan Shan, which she had leased since February 1997. She lodged an appeal against the eviction order the same day. Ms Lo then received a letter dated May 28 stating that the offence committed by Luk constituted a breach of the tenancy. The authority's appeal tribunal upheld the notice to quit on December 7. Ms Lo argues she did not know of Luk's crime. The authority is accused of not making any, or adequate, inquiry to support Ms Lo's assertion. Ms Lo and her two natural sons have continued to live in the flat pending the result of her legal action.
