Question

--------------------
The Second Party must carry out duties given to them by the First Party based on the Work Plan approved by the First Party or the *party(ies)* appointed by the First Party as stated in the mechanism of Aceh Aid, with all of their capabilities, expertise and experiences.

Answer 1

The Second Party shall carry out duties at the orders of the First Party under the terms of the Work Plan approved by the First Party or by such third parties as may be appointed by the First Party within the meaning of the Aceh Aid mechanism as having capabilities, expertise and experience in the matter.

Answer 2

Yes it is quite common to write 'party' or 'parties', and then to identify multiple parties by referring to them as "the Party of the First Part" or "the First Party", and so on. Actually, though this system seems clumsy at first, when you have a number of different people or groups being mentioned in a text, and they are all either giving or receiving some action, it is much clearer to use this system. This is so because each party is clearly defined in the beginning of the text, or as each person or group gets named in the body of the text, it is immediately assigned a party number for identification. An example: "John Jones (hereafter referred to as the First Party) is bringing a suit against John Brown (hereafter referred to as the Second Party)". . .and so on.

The precise way parties are identified will vary from court to court, but what I have given here is very common. Also, there will be differences in the different English-speaking countries.

Answer 3

I would go with " or by third parties appointed by the first party".
