Guirrith C.J. In this case the suppliants (the appellants)
claim damages against the Crown for breaches of an alleged
contract in the nature of a covenant for quiet enjoyment,
which, they contend, is contained in a pastoral lease of Crown
lands in Western Australia issued under the law in force in
the year 1887, before the grant of a Constitution to the
Colony, the alleged breaches being the issue of certain home-
stead leases and grazing leases of part of the demised land to
other persons under laws passed by the Parliament of Western
Australia after the grant of the Constitution, followed by entry
of the new lessees and dispossession of the suppliants. The Full
Court, following a previous decision in the case of Steere v. The
Minister for Lands (1), held that the homestead leases and
grazing leases were void, on the ground that the latter leases
were, if valid, infringements of the rights conferred by the
pastoral leases, and that the local Parliament was incompetent to
pass a law authorizing such dispositions of land in any way
inconsistent with titles granted before the Constitution ; but they
also held that, the leases being void, the Crown was not respon-
sible in damages for the loss occasioned to the pastoral lessee by
the entry of the homestead lessees and grazing lessees, and the
consequent dispossession of the pastoral lessee. By the law of
Western Australia a petition of right will not lie, nor can a suit
be brought in any other form against the Crown, in respect of a
tort except in a limited class of cases, which does not include such
a dispossession as that complained of. The suppliants' case must:

nature of a covenant for quiet enjoyment. The pastoral lease
uses the word "demise," and it is said that that word imports
such a covenant. This is no doubt true in the case of ordinary
leases. The covenant is, however, not express but implied. An
