The Conservation of Seals Act was enabled to protect the British seal population, but it does give allowances for the control of seals in some circumstances. It also has the following provisions for rehabilitation:
The Conservation of Seals Act, 1970, Section 9, General Exceptions:
(1) A person shall not be guilty of an offence under section 2 or 3 of this Act by reason only of—
(a) the taking or attempted taking of any seal which had been disabled otherwise than by his act and was taken or to be taken solely for the purpose of tending it and releasing it when no longer disabled;
(2) A person shall not be guilty of an offence under section 1, 2 or 3 of this Act by reason only of the killing of any seal which had been so seriously disabled otherwise than by his act that there was no reasonable chance of its recovering.
