The Wall Street Journal’s Scene Asia blog notes that Sotheby’s is policing its buyer’s in court again:

Sotheby’s […] said it was suing a man from mainland China for 27.5 million Hong Kong dollars (US$3.5 million) plus interest, an amount the auction house claims he owes for 20 works of art he won at a Hong Kong sale.

The lawsuit against Zhang Bo, whose address is in China’s Henan province, was filed over the weekend in Hong Kong’s High Court.

The works in question were all purchased at a sale of fine Chinese paintings in April. The most expensive of them is “Grazing Under the Tree” by Xu Beihong, which fetched HK$7.8 million at the sale, above the high estimate of HK$6 million. Mr. Zhang also bought “Calligraphy Couplet in Xingshu” by Zhang Daqian, one of China’s most sought-after painters, for HK$980,000.
