The Law permits such selection in cases of extreme need.

In the 1860s several colonies passed legislation to permit selection.

This fits the model described above because a new mutation (black) was required to reveal pre-existing genetic variation and to permit selection.

This permits selection of an ion with a particular m/z or allows the operator to scan for a range of m/z-values by continuously varying the applied voltage.

It permits logical selection of different processing paths, allows loops and logic branching, user-interaction and similar.

The investigations often permit selection of one mechanism from several which are proposed.

The report said such a system would increase reliability and "permit selection of the highest quality and least costly source of water."
