Where a lease of immoveable property has determined by forfeiture for non-payment of rent, and the lessor sues to eject the lessee, if, at the hearing of the suit, the lessee pays or tenders to the lessor the rent in arrear, together with interest thereon and his full costs of the suit, or gives such security as the Court thinks sufficient for making such payment within fifteen days, the Court may, in lieu of making a decree for ejectment, pass an order relieving the lessee against the forfeiture; and thereupon the lessee shall hold the property leased as if the forfeiture had not occurred.
