When an individual appeals a decision made upon evidence they feel is unfair or false, they must write a letter of reconsideration. In considering how to write a letter of reconsideration, several factors must be taken into account. The writer must strike a tone that is confident without being indignant of the decision being appealed. At the same time, the writer must craft logical arguments free from emotional appeal or hearsay in order to state their case.
Address the recipient in a businesslike manner in the introduction. Don't imply familiarity with informal titles and first names.
Continue by explaining the circumstances surrounding the appeal in a clear and concise manner. Refrain from expressing too much emotion in your writing, and avoid describing the mental and emotional effects of the decision being appealed.
Transition into the main body of the letter by listing the specific arguments that validate your request for reconsideration.
Explain the arguments for your appeal in a clear, logical manner. Be concise and to the point.
Conclude by restating your position as well as the reasons for it.
Add a caveat at the end connoting a degree of humility and goodwill (for example, I hope to continue business with you in the future, we appreciate all you've done as landlord, etc.).
Though the 'I' form is unavoidable in this format, try to minimise its use. This will force you to be unemotional and logical in your approach. Be sure to comment on the positives in your dealings with the letter's recipient. Don't simply enumerate your complaints.
