The rules of grammar become torturously complex and ultimately fail.

"This rule fails on nearly every major count by which a reasonable person would measure the actions of a Federal regulatory agency."

But to Mr. Powell, the rules have failed to live up to their promise.

Those rules have failed to prevent disastrous pension collapses like the one at United.

And in all of the tests that he had subjected them to, the rules had never failed him.

If these rules fail to determine the winner, extra time and penalty shootouts are used.

Most commonly, though, the rule fails in discrete distributions where the areas to the left and right of the median are not equal.

The rule also failed every step of the proportionality test.

Company representatives found another fault, saying the rules failed to give employers enough flexibility to change their compensation practices as the economic climate changes.

There's going to be a region where all the rules fail.
