In this circumstance, there is no viated intention from
the paying party. Thus, the paying party can only
claim that his contract with the decorator is void.
Such a claim can be done based on tort or based on
the ‘reliance damages’ of payments made through
unjust enrichment.
Those two limitations are considered by modern
scholars as an outdated theory and could no longer
apply in today’s legal system. Nowadays, the
limitations are reformulated from the ‘viated
intention’ into the ‘unintended transfer’ because
legally, the intention of the paying party is to engage
in a contractual relationship and to make a legally
binding payment. Yet, the request of restitution is
made because the contract is defective. (Vout, 2005)
In a similar vein, the second limitation is altered from
the ‘total failure of consideration’ into ‘unintended
gift’. This formulation is used when the payment
made as a result of a commercial engagement, not as
a gift. In other words, the paying party does not intend
to award a gift to the party receiving the payment.
Moreover, the modern jurists pointed out that if a
contract is void whereas one of the parties has not
made any achievements or obligations under such
contract, then the party who has not obtained the
contra-achievement may file a claim on the basis of
unjust enrichment. The claim cannot be proposed
based on the material claim because the status of the
claim is in personam not in rem, in the sense that what
the plaintiff initially demanded the performance of
the defendant's duty, not the demand to return the
payment given to the defendant.
In personam jurisdiction is a jurisdiction over
individual (person), which means that the court has
the authority in deciding the case of the defendant for
the unlimited amount and concerning all of his assets.
Meanwhile, in rem jurisdiction is a jurisdiction over
things (res) in the forum country area, which is
directly or indirectly related to the encountered case.
(Harley, 2010) However, in Indonesia, the claim that
distinguishes the in personam and the in rem lawsuit
has yet been used nor understood by legal
practitioners in Indonesia.
Based on the explanation supra, it can be derived
that the concept of unjust enrichment in the first stage
is known as one of the engagement forms that creates
rights and obligations, in addition to the commitments
arising out of the agreement. As the basis for the
emergence of the engagement, unjust enrichment
doctrine also indirectly raises the rights and
obligations of the parties for the profit and loss arising
from the state of unjust enrichment. In this case,
Kantian attempted to interpret Aristotle’s original
idea of the relationship between rights and obligations
by stating that the relationship between profit and loss
refers to as the relationship between rights and
obligations. Aristotle (1894) observed that:
‘Gain’ is what it is generally called in such cases,
even though in certain cases it is not the appropriate
term, for instance, for one who struck another – and
‘loss’ for the one who suffered-but when the suffering
is measured, it is called a loss for one party and a
gain for the other.”
Based on Aristotle’s observation above, it can also
be taken into account that the position of profits and
losses is a mutual reciprocity, that if a party earns
profits then in the other hand, another party will
receive losses. Bearing in mind such position,
Aristotle added that the corrective justice aspires the
equality between the parties, so that if there is an
event which disturbs the equality between parties and
causing unjustness, then the corrective justice seeks
to make the failing party to correct the losses that have
occurred by returning the profit to the suffering party.
By doing so, at a time the act eliminates both profit
and loss, the parties will then return to the equal
position again. (Weinrib, 2012)
Aristotle considered that it is the duty of a judge
to be able to restore justice in the form of equality
between such profits and losses among the parties.
(Harahap, 2005) Thus, the emerged profits and losses
also must have interrelated relationship. However,
this relationship will then restricts the demand for
restitution against a person, in which someone cannot
demand a refund of payment to any person as he
pleases, but these demands can only be requested to
the parties who clearly benefit from the harm he
suffers. This is what distinguishes the corrective
justice and the distributive justice, whereas the
distributive justice involves various profits and losses
in accordance with several criteria. Within
distributive justice, instead of solely putting one party
as the perpetrator and the other as the injured party,
distributive justice further divides the existing profits
and losses to all parties. Furthermore, distributive
justice does not limit itself to the relationship of two
parties, but it can also be constructed between more
than two parties. (Weinrib, 2012)
The concept of profit and loss in unjust
enrichment cannot be equalized with the profit and
loss of engagement arising from the contractual
relationship or unlawful acts. In Indonesia, the
formation of loss within its civil code originated from
the tort of unlawful acts. Based on the provision of
Article 1246 of BW, it can be seen that the element of
loss in tort consists of cost, loss, and interest.
(Muhammad, 1982) At the same time, the losses in
unlawful acts are not clearly stipulated. It is only
