So for your law report
The best method to write a report is using the IRAC method: Issue, Rules, Application, Conclusion. Where you have applied a specific law make sure to use OSCOLA citing method when adding a footnote to it.
1st paragraph/ Introduction:
Issue – what is the purpose of the report? Address the legal issue of determining what CGI’s legal rights are in terms of the 7 derivative transactions they have entered into with BM
2nd, 3rd & 4th paragraphs/ Body:
Rules – in terms of each derivative transaction the following rule applies etc etc
You will get your legal rules from the statutory provisions provided to you in the fact set, so:
All transactions are subject to an ISDA Master 2002 entered into between CGI and BM
ISDA Definitions for FX & Currency Options
ISDA Credit Derivatives Definitions (2014)
Application/ analysis – apply these laws to each transaction to determine what CGI’s legal rights are in each.
5th paragraph/ Concluding paragraph:
Conclusion – what would be the result of applying the law to each transaction? Basically, restating what you have found during the application stage. Keep it clear and concise.
