Healthy Pty Ltd is a fitness centre and retailer of sports and gym equipment who has entered into negotiations with John Hale for a lease of his commercial premises.In the proposal drawn up by the parties it was stated that John was to carry out extensive improvements of the existing structure on the site before Healthy Pty Ltd would take possession.Both parties’ licensed conveyancers enter into discussions concerning the terms of the commercial lease.These discussions were finally concluded when John’s licensed conveyancer was told that “they did not think that there would be any problems and if there were they would notify them the next day”.When John’s licensed conveyancer did not hear anything,he submitted “by way of exchange” documents executed by John for signature by Healthy Pty Ltd.
In order to complete the upgrade of the building by the required date under the contract,John organized the necessary finance and began to carry out the improvements.Healthy Pty Ltd was aware that the improvements were being carried out but were reconsidering their position in the light of a down turn in consumer spending.It was only after over 50% per cent of the work had been completed that Healthy Pty Ltd’s licensed conveyancer finally acknowledged receipt of the executed documents and advised John that their client did not intend to proceed with the lease.
Advise John on whether he has any legal rights against Healthy Pty Ltd.

Healthy Pty 是一家经营健体事业并零售健身器材的公司,该公司向John Hale 先生寻求场地租赁,双方签署草案的时候,就写到John Hale先生负责被出租场地的升级改造以达到适于Healthy Pty的经营需要.后来,双方正式讨论的时候,各自聘请的律师也加入其中,并且John Hale先生的委托律师在双方谈判最后被对方告知：Healthy Pty 一方目前对合同无任何异议,如果有的话,将会第二天立刻通知.而随后,John Hale先生一方的委托律师没有收到任何异议,并因此将合同文本交予John Hale先生,来和Healthy Pty 一方互换签字.为了履行合同中规定的升级改造之要求,John Hale先生花费了一笔开支并着手实施改造升级,而Healthy Pty 公司也知道了John Hale先生一方正在改造升级一事,但直到工程进度过半的时候,Healthy Pty 公司一方的律师才通知John Hale先生,自己的委托方不打算寻租了.请给John Hale先生提供有关他可以向Healthy Pty Ltd主张的任何法律权利.
