Damaged baggage- what is the airline's liability and how can the same be enforced

On the night of August 26, 2012, I travelled on an Air France flight from Lagos, Nigeria to Copenhagen through Paris. On arrival in Copenhagen the next morning, I was informed that due to a delay in Paris, my luggage will be delivered the next day. I reside in Malmo, Sweden.

When my luggage was finally delivered, I discovered that one of the suitcases was damaged. I called the airline's information service to complain and was asked to get a damage report from a bag shop and forward same along with other relevant documents to the airline. I did so and sent the documents through DHL courier service within the period stipulated. To my dismay, Air France has refused to respond to my complaint more than two months after it was made.

I will be graduating in December after which i will return to Nigeria.

What legal rights do I have and what are the options open to me? Can I enforce them when I return to Nigeria?

in my opinion, you have to see the dispute settlement and jurisdiction clause of the airline on your ticket or on their site.
mostly, the airline may be having an internal machinery for complaint redressal. you have to approach it first. kindly check out on the site of airline.
