The respondent (plaintiff in the main matter) sued the applicants (defendants in the main matter) arising out of a lease agreement with the first applicant for premises at Bay 5, 51A Steven Drive, Beverly West, Msasa, Harare. The second, third and fourth applicants were sued as sureties and co-principal debtors for the first applicant's obligations. The claim was for payment of operating costs incurred during occupation of the premises. The lease agreement required the landlord (respondent) to prepare estimates of operating costs at certain intervals, which were to be paid within seven days. However, no estimates were duly prepared. Around August 2009, the first applicant objected to being charged based on estimates, and the respondent thereafter charged based on actual bills sent monthly. The applicants requested further particulars on 1 August 2011, which were responded to on 15 November 2011. On 25 November 2011, the applicants requested further and better particulars. The respondent's response triggered the instant application seeking an order compelling the respondent to furnish the requested particulars.
