 Having already obtained an Act in 1805 allowing them to enclose and develop of common land within the manor, the College was granted the power by the 1808 Dulwich College Building Act to extend the period of which leases ran from twenty-one years as laid down by Alleyn, to eighty-four years, thus attracting richer tenants and bringing in vast sums of money.The additional wealth of the College eventually resulted in the Charity Commission setting up an enquiry into the advisability of widening the application of the funds to those extra beneficiaries Alleyn had specified in later amending clauses to the foundation's original statutes.Although the Master of the Rolls, Lord Langdale rejected the appeal in 1841 on the grounds that Alleyn had no right to alter the original statutes, he did express dissatisfaction with the college's provision of education.
