Jerry Yang of Yahoo did not need to read the judgment of the House of Lords in Walford v Miles (1992) 2 AC 128 to appreciate the principles of commercial negotiations.
Lord Ackner remarked in the case:
[a party] â â¦to the negotiations is entitled to pursue his (or her) interest, so long as he avoids making misrepresentations. To advance that interest he must be entitled, if he thinks it appropriate, to threaten to withdraw from further negotiations or to withdraw in fact, in the hope that the other party may seek to reopen the negotiations by offering him improved terms.â?
