It would be pragmatically odd to put a 3SG pronoun before i luk ('it seems'), i.e. it would generate various additional implicatures (such as that the speaker wants to talk about a particular law, which is clearly not the case in this example).
There is considerable discussion in the literature on Bislama (and related languages) about what the best linguistic characterization of i (as in i luk) is. Meyerhoff (2000a) considers the various analyses that have been proposed and argues from the distribution of single pronoun, focused pronouns and null subjects that i (and oli) are not pronominal. Meyerhoff (2000a, b) calls them 'agreement', another reasonable alternative is 'predicate marker' (if it is understood that the form of the marker is related to the persona and number of the subject).
