Wal-Mart facing troubles?

Wal-Mart facing huge pay discrimination suit.

While the article points out that the court ruling was a "sharply divided" one (6-5), I take away from this:

-Wal-mart has lost on this issue three times already

-Their defense seems to rest on the fact that the problem is too big for them to defend.

It also seems to me, that if the 6 defendants are not representative enough to enjoy (or, in this case, initiate) class-action status, then that will make it that much harder for them to prove their point that Wal-mart has a pervasive and discriminatory policy with regard to the treatment of its female employees.

But there you go.
