2. INTERFERENCE WITH USE AND ENJOYMENT
Private  nuisance  is  a  balancing  act  between the  defendant’s  right  to  use  their  land  as  they wish  and  the  claimant’s  right  to  enjoy  their land  without  interference. The  claimant  must  establish  that  the defendant  has  caused  a  substantial interference  with  their  use  or  enjoyment  of their  land. No  account  is  taken  of  trivialities.
The interference  may  take  a  number  of  forms  but some  of  the  commonest  are;
Injury to Property, Any unlawful interference with a person’s use or enjoyment of land through some object which cause damage to the property is actionable as nuisance. It may be allowing the branches of a tree to overhand on the land of another person, or the escape of roots of the tree, water, gas, smoke or fumes, etc. on the neighbor’s land or even by vibration.  The right of every owner of land such land in its natural conditions, shall have support naturally rendered by the subjacent and adjacent soil of another person. A person has natural right to have his land supported by his neighbor’sand therefore removal of support, lateral or form beneath is a nuisance. The natural right of support of neighbor’s land is available only in respect of land without buildings.
Therefore, such a right is not available in respect of building or other structure of land. Although the law does not recognize the right of support of building, yet if the damage to the building is consequential to the damage to natural right of support of land, an action for withdrawal of support can lie.

Injury to comfort or health, Substantial interference with the comfort and the convenience in the using the premises is actionable as a nuisance. A mare trifling or fanciful inconvenience is not enough. The law does not take account of very trifling maters. There should be a serious inconvenience and interference with the comfort of the occupiers of the dwelling house according to notions prevalent among reasonable man and woman. The standard of comfort varies from time to time and place to place. Inconvenience and discomfort from the point of view of a particular plaintiff is not the test of nuisance but the test is how an average man residing in the same area would take it. The plaintiff may be over sensitive.
Whether  the  interference  amounts  to  a  nuisance  is  a question  for  the  court. Normally  this  will  be  determined  by  applying  a reasonableness  test,  but  where  the  interference causes material  damage to  the  claimant’s  land,  the defendant  will  be  liable  unless  the  claimant  is  oversensitive  or  one  of  the  defenses  to  nuisance  applies. In St  Helens Smelting  Co  v  Tipping (1865] 11  HL  Cas  642, The  plaintiff  bought  an  estate  near  to  the  defendant’s  copper smelting  works. Fumes from  the works  damaged  the  plaintiff’s  trees  and  crops. The court  drew a distinction  between nuisances  causing material damage  to  the  land  and  those  which  caused  sensible personal discomfort. In  the  latter  case  the  question  of  locality  was  relevant.  As  the  plaintiff’s  land  had  suffered  material  damage,  the fact  that the  locality  was  a  manufacturing area  was  irrelevant  and  an injunction  was  granted. The  problem  with  this  decision is  that  it  is  difficult  to determine  what  is  meant  by  material damage. Any  substantial  interference  with  residential  land  may  lower its  value,  but  unless  the  land  itself  is  damaged  the  locality factor  may  defeat  the  claimant’s  action. (Emphasis  supplied).
In  Tanzania  the  case  of Sandhu  Construction  Company Limited  v.  Peter  E.M.  Shayo (1984] TLR  127 (CA) is  authoritative  on  the  issue  of interference,  reasonableness  and  locality. In  this  case  the  respondent  had  sued  the  appellant  in  private nuisance  and  prayed  for  an  injunction  to  restrain  the  appellant from  continuing  the  nuisance  and  for  general  damages.   The respondent  had  alleged that his  enjoyment of  his  house situated  at  Elerai  village  in  the Arusha Municipality  was  seriously interfered  with  by  the  excessive  noise,  vibrations  and obnoxious dust  emanating from  a  stone  crusher operated by  the  appellant situated  30  metres  from  his  house. The respondent himself  had  a  maize  mill  operating within  the compound  of  his  house.  The  respondent  was  successful in  the  High  Court  and  it  is  against that  decision  that  the  appellant  is  appealing.
The  Court  of  Appeal  as  per  Mustafa  JA  (as  he  then was)  held  that: In  considering  the  standard  of  comfort  or  convenience  of living   of  the  average  man,  the  character  of the neighborhood  must  be  taken  into  account;  an  average man's  standard  of  comfort  and  convenience  involves  the toleration  of  acts  done  by  his  neighbour  in  the  course  of ordinary  and  reasonable  use  of  his  property; a  nuisance  to  be  actionable  must  be  such  as  to  be  a  real interference  with  the  comfort  or  convenience  of  living according  to  the  standard  of  the  average  man;  discomforts caused  are  not  actionable  if  they  fail  to  qualify  as intolerable  or  unacceptable;  the  discomforts  must  cause suffering  to  the  party  complaining.

3. DAMAGE
Actual damage is required to be proved in an action for nuisance. In the case of public nuisance, the plaintiff can bring an action in tort only when he proves a special damage to him. In private nuisance, although damage is one of the essentials, the law will often presume it.

4.NUISANCE ON HIGHWAY
Obstruction on highway or creating dangers on it or on its close proximity is a nuisance. Obstruction need not to be total. The obstruction must, however, be unreasonable. Thus to cause the foundation of queues without completely blocking the public passage is a nuisance.                   In Ware v. Garston Haulage Co. Ltd, the defendant left his lorry with an attached trailer by the side of highway. The trailer had no rear light in the night and the plaintiff on his motor cycle ran into the back of the trailer. In an action by the plaintiff against the defendant for nuisance. It was held that defendant was liable as his leaving the vehicle in the darkness on the highway. Leaving a vehicle a place for an unreasonable long time even during the day has been held to be nuisance. Creation of dangers on the highway by making excavations, projection of tree or lamps, leaving slippery or dangerous substance on the road also amount to nuisance. Doing an act in one’s own premises, even though that offends the sentiments of the passer-by of a person is not a nuisance.

Projections
As regards projection on highway by object like overhanging branches of tree or a clock, etc. from the land or building adjoining the highway, no action for nuisance can be brought for such projection unless some damage is caused thereby. The mare fact that some object projects on the highway does not mean that is a nuisance. If every projection was to be considered to be nuisance, it would seem that, a fortiori every lamp so overhanging, every signboard, every clock every awning outside a shop, are in themselves illegal erection, not to mention the upper storey corbelled out over the roadway, which were common in every town of country. In Noble v. Harrison [1914] K.B. 30, the branch of a beach tree growing on the defendant’s land hug on the highway to a height of about 30 feet above the ground. In fine weather, the branch of tree broke down and fell upon the plaintiff vehicle which was passing along the highway. For the damage to the vehicle plaintiff sued the defendant to make him liable for nuisance.
The right of the public in a highway was merely to pass so long that right was not interfered with, they could not complain of what was in the air above or on the earth beneath. If the occupier of the premises knows of the defects in the projection but he does not get the same removed, he would be liable. It is no answer to an action that he had employed an independent contractor to remove that defect but the same was not done properly.

REMEDIES AVAILABLE FOR TORT OF NUISANCE
        i.            INJUNCTION
The  injunction  is  the  primary  remedy  in  nuisance  actions  and  its objective  is  to  force  the  defendant  to  cease  their  activities. The  injunction  may  be  perpetual  and  terminate  the  activity  or  limit it  to  certain  times. It  is  possible  for  the  court  to  suspend  the  injunction  and  give  the defendant  the  opportunity  to  eliminate  the  source  of  the complaint. Injunctions  are  equitable  remedies  and  as  such  are  not  available as  of  right.The  question  of  when  the  court  should  exercise  its  discretion  to refuse  an  injunction  was  considered  in  the  following  case:
In Shelfer  v  City  of  London  Electric  Lighting  Co 1895]  1  Ch  287, Vibration  and  noise  were  caused  by  the  defendant’s  activities. The  defendant  claimed  that  the  plaintiff  should  be  limited  to damages  as  the  award  of  an  injunction  would  deprive  many Londoners  of  electricity.
The  court  held  that  the  discretion  not  to  award  the  injunction should  be  exercised  only  in  exceptional  circumstances:  (a)  where  the  injury  to  the  plaintiff’s  legal  right  is  small;  and (b)  is  capable  of  being  estimated  in  money  terms;  and (c)  is  one  which  can  be  adequately  compensated by  a  small money  payment; and (d)  it  would  be  oppressive  to  the  defendant  to  grant  an  injunction.

      ii.            DAMAGES
In  public  nuisance  actions  the  claimant  must  prove  special damage  in  order  to  succeed. Damage  must  usually  be  proved  in  a  private  nuisance  action  but may  be presumed. It  is  normal  for  the  claimant  to  seek  damages  for  past  losses  and an  injunction  to  prevent  future  losses. The  remoteness  of  damage  test  in  nuisance  is  the  same  as  that in  negligence:  the  defendant  must  have  been  able  reasonably  to foresee  the  kind  of  damage  which  occurred.  ( 2 Wagon  Mound No [1967]  1  AC  617.) Where the  nuisance  causes  damage  to  the  land,  the  measure  of damages  will  usually  be  the  depreciation  in  value  of  the  land. Where the  nuisance  consists  of  interference  with  use  and enjoyment,  then  assessment  of  damages  presents  problems. In Bone  v Seale (1975] 1  All  ER  787,The  defendant’s  pig  farm  was  adjacent  to  the  plaintiff’s  land. The  plaintiff  sought  an  injunction  and  damages  in  nuisance  in respect  of  smells  caused  by  pig  manure  and  the  boiling  of  pig swill.
The  court  held  that  there  was  no  damage  to  the  plaintiff’s property  or  his  health  and  awarded  damages  of  £1,000 based  on the  amount  that  would  have  been  awarded  in  a  personal  injuries action  for  loss  of  sense  of  smell.

ABATEMENT
This  remedy  of  abatement  is  a  form  of  self help  and consists  of  the  claimant  taking  steps  to  stop  the nuisance,  for  example,  by  cutting  off  the  branches  of overhanging  trees  or  unblocking  drains. Where the  exercise  of  the  remedy  requires  the claimant  to  enter  another  person’s  land,  then  notice must  be  given,  otherwise  the  abator  will  become  a trespasser. It  is  fair  to  say  that  the  law  does  not  usually  favour this  remedy  and  in  most  cases  it  is  not  advisable. ( Delaware  Mansions  Ltd Council [2002]  1  AC  321.)

DEFENCES IN TORT OF NUISANCE
General defenses apply to most torts, there are some tort where only certain defenses are accepted and nuisance is one of them! Some of the defenses recognized by the courts as valid defenses and some other have been rejected.  The following defenses are considered valid in nuisance cases:-
1. Statutory Authority
If the act said to be causing unreasonable interference, or it is related to, an unauthorized under a statute, there can be no claim of private nuisance. There is no liability for that under the tort. 
2. Prescriptive  Right
Law recognizes that if for a long period of time plaintiff has not objected to an act that potentially disturbing, then the plaintiff cannot, after such passage of time, turn around and complain of the act. The period of time to acquire this right to continue with the activity is 20 years.
For instance if you live next door to musician for 20 years, and he has been playing his drums every morning without complaint from you, then you are not entitled to complain about it in the 21st year. The musician has an prescriptive right to do the act that you claim to be a nuisance. In Sturges  v  Bridgman [1879]  11  Ch  D  852,The  defense  of  prescription  failed,  as  the  noise  from the  confectioner’s  activities  only  became  a  nuisance when  the  doctor  had  his  extended  consulting  room built. Only  from  this  time  did  the  20  years  start  to  run.
3. Usefulness
Usefulness  is  simply  the  question  of  public utility  as  a  defense,  rather  than  a  factor  going towards  reasonableness. The  fact  that  the  defendant’s  activity  is  a useful  one  is  not  a  defense.
4. Nuisance  due  to  many
Where  the  nuisance  is  caused  by  a  number of  persons,  it  is  not  a  defense  for  the defendants to  prove  that  their  contribution alone  would  not  have  amounted  to  a nuisance.Coming  to  the  nuisance is  not  a  defense. The defendant  cannot  argue  that  the  claimant  was aware of the nuisance when they moved to the area. In Sturges  v  Bridgman (1879)  11  Ch  D  852 ,the  confectioner  argued  that  when  the  doctor  built his  extended  consulting  room  he  was  aware  of  the noise  and  had  therefore  come  to  the  nuisance. The  court  rejected  this  argument  as  this  was  not  a recognised  defense  in  nuisance. In Miller  v  Jackson [1977]  QB  966 , Lord  Denning argued  that  as  the  plaintiffs  had  bought  a house  next  to  a  cricket  field  they  could  not  be heard  to  complain about interference by cricket balls. This  was  rejected  by  the  rest  of  the  Court of Appeal  so  far  as  establishing  a  nuisance  was concerned, but  it  was  a factor  in  the  decision of  the  majority  not  to  grant  an  injunction.
