People hardly sue here, that is the reason some corporation could trample on people's right.

I couldn't agree more. Until people know their rights and fight for it, they will lose a lot in life. Trust me. I understand the place of poverty of many Nigerians. However, such people could visit some NGO law firms that could help them.
There is a case at hand, where apparently an extract of the law has been misinterpreted. My attorney is working on the case. Yes, it is costing me money. I don't expect my lawyer to defend me for free. Justice is what I seek for. The injustices in this world is too much. Like you rightly stated

I think if one of them is made an example of and sued and made to pay till they declare bankruptcy, then others may sit up to avoid a similar fate.

Yes, someone needs to be made a scapegoat to serve as a deterrent to others. Even if you don't want to sue outrightly, you can at least appeal your case, I think.
