Christchurch property developer David Henderson says it is "the end of the line" for one of his battles with the taxman after his appeal was thrown out by the Supreme Court.
Henderson's long and difficult relationship with Inland Revenue has spanned more than 17 years.
Highlights include the developer's win over the IRD in 1999 after it claimed he owed $1 million in unpaid tax.
The IRD eventually admitted getting its facts wrong but not before Henderson was declared bankrupt.
Henderson went on to buy the IRD's seven-storey office in Christchurch.
