consideration need not be adequate
this is a pragmatic (practical) response to the question of how consideration should be enforced - some may consider the chocolate wrappers with no real world value in Chappell v Nestle being considered sufficient to be ridiculous however the courts role should not be to intervene and add value just because of a bad decision - this allows commerce to operate without constant legal interference - there is also the question of whether this has been undermined by williams v Roffery where extra money was offered to meet a deadline but no real consideration was given
uncertainty
clear differences in Stilk v Myrick and Hartley v Ponsonby cause grey areas - what if 7 had deserted for example - where does the judge draw the line - makes the law subjective and up to the discretion of judges
past consideration is no consideration
the current ruling is that it is required that the reward be contemplated by the parties before the act is complete - this however can be subjective and dependant on judges - this means there is a lack of clarity - however this is justified by the fact it closes the floodgates to dubious cases
Reforms
1) ensure every contract has fair value - meaning consideration must be sufficient and adequate - unless the state controlled all business this would be impractical and too great an interference in the market and freedom of contract - this could lead to situations where companies could be sued for selling goods at a higher price - this is not the purpose of the law
2) the rule of past consideration is no consideration should be abolished - however although unfair outcomes may be present this rule creates certainty with regards to evidence in the courts
