If you find just preparing the record is taking hours of extra time, stop and think carefully about what you are doing. Something is wrong with your methodology. As to the memo, you only need to use as many words as it takes to record the results of your research accurately and clearly. All the research requests have relatively clear answers. It may be that your problem does not expressly ask you to consider the law of England and either Canada or Australia, as well as the law in Hong Kong.
Some problems specifically identify Australia or Canada.
Make sure you research the correct jurisdiction. Some students have asked whether they should use paper or electronic versions if they are able to find both. Use the version which you are able to bring most up to date. If you do use an electronic version, give the url and short title in your typed research guide and use the short title only on your photocopy and in your memo. The individual research assignment details will be distributed this week.
