Question: There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

Answer: When are most of the problems created that might result in an otherwise valid treaty being rejected as a binding international agreement?


Question: The major settlements in the ceremonial county are concentrated on the Fylde coast (the Blackpool Urban Area), and a belt of towns running west-east along the M65: Preston, Blackburn, Accrington, Burnley, Nelson and Colne. South of Preston are the towns of Leyland and Chorley; the three formed part of the Central Lancashire New Town designated in 1970. The north of the county is predominantly rural and sparsely populated, except for the towns of Lancaster and Morecambe which form a large conurbation of almost 100,000 people. Lancashire is home to a significant Asian population, numbering over 70,000 and 6% of the county's population, and concentrated largely in the former cotton mill towns in the south east.

Answer: Where are the major settlements in the ceremonial county located?


Question: From 1962 until his retirement in 1968, he was a professor at the University of Freiburg, West Germany, where he began work on his next book, Law, Legislation and Liberty. Hayek regarded his years at Freiburg as "very fruitful". Following his retirement, Hayek spent a year as a visiting professor of philosophy at the University of California, Los Angeles, where he continued work on Law, Legislation and Liberty, teaching a graduate seminar by the same name and another on the philosophy of social science. Primary drafts of the book were completed by 1970, but Hayek chose to rework his drafts and finally brought the book to publication in three volumes in 1973, 1976 and 1979.

Answer:
What country did Hayek move to in 1962?
