My question involves criminal law for the state of: UK
L lives in an apartment under lease. L raises dispute with service charge. F (freeholder) initiates legal action to recover service charge, which L defends. In defence L shows that F cannot recover service charge as F has not complied with statutory requirements and the time period (18 months) for issuing a valid invoice has passed. Defence is backed up by copies of previous LVT decisions which lay this out in an unambiguous manner. F withdraws action citing 'irregularities in invoices' as reason.
F then approaches L's mortgage provider claiming sums are owed and demanding payment. Does this constitute fraud?
