Accordingly, in addition to the other reasons which my Lord has mentioned, with which I fully agree, for this reason also I should have held that the second argument put forward on behalf of the second defendant cannot succeed.
38 In Annen v. Rattee [1984] 1 EGLR 136, the plaintiff and a Mr. Wager were co-owners of a flat. Mr. Wager and the defendant resided in the flat, but the plaintiff did not. In September 1977, Mr. Wager granted the defendant an oral licence to occupy the flat, which she did with other people. In 1980, the plaintiff went into the flat in an attempt to displace the defendant, but was unsuccessful. The plaintiff then purported to terminate the defendant's licence, and took proceedings for possession. The Court of Appeal upheld a decision in favour of the plaintiff. Stephenson LJ and Lloyd LJ held that this decision was supported by Summersett and Robson-Paul.
39 In Hong v. Choo [2004] HKEC 64, the plaintiffs were four of five tenants in common of a property, the fifth share being held by a family member who died in 1995. The administrators of that person's estate authorised another family member to occupy the property as their agent, on a non-exclusive basis, pending the sale of the property and possession being given to the buyer. The plaintiff sought possession and damages. The Court dismissed the proceedings. It distinguished Robson-Paul on the basis that the ratio of that case was that the licence purportedly given to Ms. Dimitriou was to possess the property to the exclusion of the plaintiff, and a tenant in common had no authority to give such a licence; and said that Annen was inconsistent with Bull v. Bull, and did not follow it. The Court continued at [78]:
78. Having considered these principles and the authorities, I think it is well within the power of a tenant in common to possess, occupy and enjoy the use of a property with his other tenants in common on a non-exclusive basis. As long as he does not exceed his boundary of non-exclusive user, he is not guilty of trespass and the other tenants in common cannot turn him out. He may also grant a licence to his licensee to possess, occupy and enjoy the use of the property on the same basis. Thus, insofar as a licence granted by a tenant in common which does not purport to give exclusive possession of the property to the licensee, it cannot be validly terminated by the other tenants in common without his consent, just as much as tenant in common is not entitled to turn out the other if the other is properly enjoying the property within the boundaries of his rights as a tenant in common.
40 In my opinion, the Hong Kong case is incorrect insofar as it asserts that, so long as a licence granted by a tenant in common does not purport to give exclusive possession, such a licence may both authorise another person, in the absence of the grantor and for an indefinite period, to do whatever a tenant in common can do, and also not be terminable by other tenants in common of the property. In my opinion, that gives too little weight to an incident of possession, namely the right or power to grant or withhold permission to others to enter property. Although one tenant in common can transfer or lease its interest, I do not think one tenant in common can, without such a transfer or lease, grant a licence to another, irrevocable by other tenants in common, if that licence is of a kind that goes beyond what is reasonable and incidental to the grantor's possession and use and enjoyment of the property in common with the other tenants in common, and which interferes with the possession and use and enjoyment of the property by other tenants in common.
41 For example, suppose there are two tenants in common of a small house, and one of them purports to grant a licence to twenty people to live in the house. If this amounted to excluding the other from possession, it would be a trespass; but if it fell short of excluding the other person, but was substantially detrimental to the other tenant in common's use and enjoyment of the property, in my opinion such a licence could be terminated by the other tenant in common, assuming that it went beyond what was reasonable and incidental to the grantor's possession and use and enjoyment of the property. That is, in my opinion, any licence in excess of what is reasonable and incidental to one tenant in common's possession and use and enjoyment of the property, and which prejudices the other tenant in common's possession and use and enjoyment of the property, is a licence terminable by the other tenant in common. Otherwise, in my opinion, there can be no reasonable reconciliation of the rights of both tenants in common to have possession and use and enjoyment of the property.
42 On that basis, the result in Robson-Paul is correct. If there was a licence to use the premises to the exclusion of the plaintiff, that was clearly a licence that could not be granted; but if the licence fell short of that, but was a licence to continue for an indefinite period to exercise all the rights of one tenant in common, without a transfer or lease, it would be a licence going beyond what was reasonable and incidental to the grantor's possession and use and enjoyment of the property in common with the plaintiff, and so was terminable by the plaintiff.
43 In my opinion, the result in Annen v. Rattee is probably correct on the same basis. In my opinion, that case was wrong in so far as it applied to cases concerning periodic tenancies granted by joint tenants, and insofar as it suggested a licence granted by one tenant in common could always be terminated by another. But it was open to conclude that the licence granted in that case was so extensive as to be terminable by the other tenant in common.
44 In my opinion, the result in Hong v. Choo was also correct. The tenant in common was dead, and the administrators of his estate wished to have a representative occupying the property, and they authorised the family member who had lived in the house with other family members to stay at the house pending the sale. In my opinion, that was reasonably incidental to that tenant in common's right to possession and use and enjoyment of the property, and so was not terminable by other tenants in common.
45 Applying this approach to the entrance foyer of an apartment block, and subject to any bylaws of a relevant strata scheme, this would mean that, if one unit owner gives a licence to an acquaintance to enter the common property in order to visit the unit owner's unit, that licence could not be revoked by another unit owner.
46 On the other hand, one unit owner could not give a licence, irrevocable by another unit owner, to a person who sought entry in order to harass the other unit owner at the internal front door of the latter's unit. That licence would not be reasonable and incidental to the right of the grantor to possession and use and enjoyment of the common property. The grant of such a licence could not trump the right of the person who would be harassed to exclude the harasser, as an incident of that person's right to possession and use and enjoyment of the common property.
47 Turning to the facts of this case, entry to the common property was denied by the plaintiff and Ms. Docherty.
48 As regards Ms. Docherty, in my opinion she, being lawfully under restraint pursuant to s.5 of the Intoxicated Persons Act, did not have power to deny entry, if the police otherwise had a licence to enter. That is, in my opinion the authority given to police by s.5 to override an intoxicated person's freedom of movement implies an authority to override that person's wishes as to entry on to property.
49 As regards the plaintiff, the onus was on the police to show a right to enter, and the police did not show that the plaintiff was not a unit owner with a right to possession of the common property as a tenant in common with other unit owners. Permission to enter was purportedly granted by whoever unlocked the front door, but the question is whether that permission trumps the refusal of permission by the plaintiff. It was not shown that it was the occupiers of Ms. Docherty's unit who unlocked the front door, so the question has to be considered on the basis that whoever unlocked the front door had no connection with the events other than having information that people claiming to be police wanted to enter for an undisclosed reason. In my opinion, it is not shown that such licence as may thereby have been granted or purportedly granted was reasonable and incidental to the purported grantor's possession and use and enjoyment of the common property, in such a way as to be irrevocable by other tenants in common, particularly the tenant in common in place at the front door itself.
50 For those reasons, in my opinion the police did not have a licence to enter, and were trespassers when they did so unless the entry was otherwise justified.
51 Because Ms. Docherty did not have power to revoke a licence given to the police to enter, the police were not trespassing when they went to the front door. Indeed, I think the implied licence to the police to go to the front door for legitimate purposes, granted by all tenants in common, was not in any event revocable by one tenant in common. I am also inclined to think that, if the police had proved that they were given permission to enter by an owner of the unit occupied by Ms. Docherty for the known purpose of receiving Ms. Docherty from the police, that would have been a licence not revocable by other unit owners, because it would be a licence that was reasonable and incidental to the rights of a tenant in common.
